07:57 – I finished the first lab session in the forgery group yesterday, on detecting alterations in documents, and started the lab session on analysis of inks by chromatography. I’ll finish that today and start on the final lab session in that group, on analysis of papers. Then it’ll be on to forensic biology.


I predicted recently that the Financial Crisis item would re-appear on the Hot Topics menu bar of The Telegraph, and a week or so ago it did. Things in euroland have been lurching from worse to horrible over the last couple of months. Merkozy is no more, with French voters electing Hollande to replace Sarkozy. Greece is in complete chaos after last week’s elections, unable to form a government. The new Greek bonds are now trading at 20%+ yields. Spain and Italy are again paying disastrously high yields on their bonds, and Spain is teetering on the edge of seeking a bailout. The German government refuses to make any further concessions, and is now saying openly that it’s time for Greece to leave the euro. I said a year ago that Europe could do nothing to prevent the collapse of the euro, and that any stopgap measures they implemented could only delay the collapse for a short time at huge expense. And that’s exactly what’s happened and what’s still happening. Two years ago, even one year ago, the EU authorities could have minimized the damage simply by admitting that the euro was a fatally-flawed idea and allowing the eurozone to break up naturally. Now they’ve dug themselves in so deep that the collapse, when it comes, is going to be catastrophic. And there’s no longer anything anyone can do to prevent that catastrophe. Expect to see yet another Greek default, probably in the next couple of months, that’ll set the row of dominoes falling one after the other. Things are going to get even uglier.

07:31 – Only two groups of lab sessions left to re-write, one on forgeries, which I started yesterday, and one on forensic biology. I hope to have both of those finished by the end of next week, which’ll leave me a couple weeks to work on the front matter and on doing a final quick pass through the entire manuscript.

07:25 – Amendment One passed 61% to 39%. Barbara said this morning that she’s about to give up on voting. What’s the point, she asks, when a contemptible measure like Amendment One can be not just passed but passed by a landslide? The Southern Baptists are very proud of themselves. Bastards.

Although this was referred to as the “Gay Marriage” amendment, it’s much more than that. Gay marriage was already illegal in North Carolina, more’s the pity. This amendment forbids the North Carolina government from recognizing any relationship other than a marriage between one man and one woman, including civil unions and domestic partnerships. So now the state of North Carolina is officially opposed not just to human decency, but to the US Constitution as well. Expect a series of expensive, drawn-out legal challenges, ultimately concluding with the repeal of this obnoxious, evil, and unenforceable Amendment. All thanks to religious nutters and their insistence on forcing their twisted beliefs on everyone else. Bastards.

07:25 – Election Day today. Ordinarily, I wouldn’t bestir myself because there’s nothing on the ballot of much interest. Except Amendment One, the hateful attempt to write discrimination against gay people into the North Carolina Constitution. Unfortunately, if one believes the polls, this contemptible piece of fundie slime is likely to pass. Well, if it does, it’ll be despite Barbara’s and my votes.

I don’t understand how any decent human being could vote in favor this amendment. The obvious answer is that they couldn’t. As long as they were at it, I don’t understand why these fundie assholes didn’t expand the language of Amendment One to require Jews to live in ghettos and wear yellow stars of David. Hey, come to think of it, they could also have included language to return all these descendants of slaves to their rightful owners. Geez.


09:55 – Well, that was interesting. I just took Colin for a walk down to the corner. As he was sniffing around the corner yard, what should he notice but an evil C-A-T lying in Kim’s yard next door? So Colin tried to pull me over to see the evil C-A-T, but I forced him to stay near the curb. When we arrived in front of Kim’s house, the evil C-A-T was still lying there near the house, about 50 feet (15 meters) from the street and a couple meters from the walk between the street and Kim’s front door. Colin and the evil C-A-T stared at each other for a minute or so, with neither of them moving.

Then, apparently deciding that with the cat distracted it was a good time to make a break for it, a chipmunk sprang out of the grass near the evil C-A-T and made for Kim’s walk. The evil C-A-T pounced and missed, and the chipmunk sprinted down Kim’s walk toward Colin, with the evil C-A-T in hot pursuit. Apparently, the evil C-A-T realized that charging into Colin’s range wasn’t a good idea, because it clamped on the brakes and skidded to stop. Meanwhile, the chipmunk ran right up to Colin, noticed that it’d escaped one predator only to approach a Fearsome Predator. It scurried into the grass next to the walk. Colin approached it closely to sniff it, but took no hostile action. Eventually the chipmunk just couldn’t take it any more, so it made a break for the walk and ran down the walk the few feet to the street. Colin, of course, was in hot pursuit.

But, as I’ve said before, Border Collies have had all the kill instinct bred out of them, so Colin showed no interest in the chipmunk as a potential meal. Instead, he herded it, circling around it and crouching just as he would for a sheep that wasn’t cooperating. The chipmunk dashed this way and that, with Colin cutting it off at every turn. Eventually the chipmunk, snuggled up right against my boot, where it was apparently ready to put down roots. I called Colin off. Well, actually, I pulled him off. The chipmunk jumped up on the curb and scampered down toward the corner, with both Colin and the evil C-A-T watching its progress.

Then the evil C-A-T rose and began stalking toward the chipmunk. Incredibly, Colin moved to block the evil C-A-T, protecting the chipmunk. I am not making this up. Each time the evil C-A-T moved toward the chipmunk, Colin moved to put himself between the evil C-A-T and the chipmunk. Apparently, the fact that Colin had been herding that chipmunk for a minute or so was sufficient to make the chipmunk a member of Colin’s flock. So naturally, he had to protect a flock member from a predator, which he did in spades. Eventually, the evil C-A-T gave up. Colin watched the chipmunk finish its journey to the corner and go down a storm drain, and then we walked home.


11:07 – When I voted at 10:15, I was voter number 172 for our precinct. That’s a pretty heavy turnout for that early in the day for a primary election. That’s good news, because a light turnout skews things in favor of older people, who tend to vote regardless and also tend to support Amendment One. The heavy turnout favors issues supported by the less dedicated voters. Unfortunately, it’s started to cloud up and drizzle, which tends to discourage liberals, young voters, and others who’d tend to oppose Amendment One. Still, I’m cheered by the relatively high turnout so far. In past primaries when I voted around the same time of morning, I’d usually be voter number 60 or thereabouts. At least so far, the turnout appears to be two or three times heavier than usual.

07:35 – I finished the group on impression analysis yesterday and got started on the group on gunshot and explosive residues analysis. I had intended to include with the kit tiny specimens of firearms propellants (smokeless powder, black powder, Pyrodex) and explosives (dynamite, RDX, PETN, and so on). By “tiny”, I mean specimens of maybe 50 mg. Call it a tenth the size of an aspirin tablet. I was surprised to find that it’s illegal to mail these things. Not just under the Small Quantity Exemption, but period.

Fortunately, I checked the SQE rules. Until now, all of the hazardous materials I’ve been including the kits has fallen under paragraph 334.2(a) or 334.2(b), which qualify up to 30 mL or 30 g of material, respectively, for shipping under SQE. Paragraph 334.2(c) exempts “1 g (0.04 oz) or less for Division 6.1 (Packing Group I) materials”. I wasn’t sure what was included in Class 6 until I looked it up. It turns out to be “Toxic substances and infectious substances”. Alas, explosives (including firearms propellants) are in Class 1, for which there is no SQE (or ORM-D) waiver. That means it’s simply illegal to mail Class 1 materials, no matter how small the quantity. So I’ll have to fall back on telling readers to get their own specimens, which actually isn’t as difficult as it seems at first glance.

Barbara and I have started watching the shortened season three of Crossing Jordan on Netflix streaming. (The actress who plays Jordan was pregnant, which resulted in a season of only 13 episodes.) Fortunately, I happened to notice a post on a forum that mentioned that NBC had run season three not just out of order, but *really* out of order. So, instead of watching the episodes in the order they were broadcast, which is the order that Netflix streaming has them in, we’re watching them in the order they were intended to be broadcast:

1. episode #13
2. episode #7
3. episode #3
4. episode #1
5. episode #12
6. episode #2
7. episode #4
8. episode #9
9. episode #5
10. episode #6
11. episode #11
12. episode #8
13. episode #10

08:26 – Barbara is cleaning house this morning and then heading off to her parents’ house for lunch. She’ll make a small Costco run on her way home.

I’m still working on the impression analysis lab sessions. Once I finish this group, all that remains are the groups on gunshot and explosives residues, forgeries and fakes, and forensic biology. Those and the front matter. I’m hoping to finish all of those with several days to spare before the 31 May deadline so that I can go back and do some polishing before submission and maybe even add a lab session or two.

I’ve been issuing purchase orders for materials for the forensic kits as I finish each group of lab sessions, so I’ve already accumulated a lot of stuff. The only exception is the chemical orders, which I’ll combine once I know everything I need to order.

08:13 – Barbara spread about 3,058,180 mL of the mulch yesterday, leaving a gigantic 37 mL (2+ tablespoons) pile of the stuff in the driveway. While she was working, we had Colin on a tie-out in the front yard. Someone came down the street walking a dog, and Colin charged out to see them at a dead run. So much for that collar. The plastic quick-release snap connector fractured. We have a drawer full of old collars, and I was going to replace Colin’s collar with a very robust one that used a standard buckle instead of a quick-release plastic snap connector. Barbara pointed out that if Colin had been wearing one of those he might have broken his neck. So we replaced his collar with another snap connector model.

I finished up the bloodstains stuff yesterday and got started on the group of lab sessions on impression analysis. If I have time, I’m going to add a session to that group. Just about every recent cop show has the cops standing around a whiteboard in the squad room, using dry-erase markers to add information to it. Well, it may surprise some people to know that criminals are also big users of whiteboards and dry-erase markers. And, like most people, criminals usually use erasers to erase the stuff on those whiteboards.

But using an eraser on a whiteboard doesn’t actually erase what’s on it. All it does is remove the microscopically thin layer of dried ink powder, leaving traces of the carrier on the board. Those traces can be dusted with fingerprint powder to make them readable. Although I can’t find anything in the literature about using iodine fuming to make those latent traces visible, I suspect that might work at least as well as dusting. I’ll try it. Meanwhile, smart criminals use a paper towel soaked in isopropanol to wet-erase their dry-erase boards. I’ve already tried that, and found that it makes dusting useless to recover latent traces.

07:27 – I finished the group of lab sessions on revealing latent fingerprints yesterday, and got started on blood. I think we’ll include only one or two sessions on revealing bloodstains. The problem is that, with the exception of Kastle-Meyer reagent, blood reagents are (a) extremely expensive, too much so for a kit, and/or (b) very hazardous, and/or (c) require specialized equipment like a forensic alternate light source, and/or (d) just don’t work very well. Meanwhile, stuff for the forensic science kits is starting to accumulate in large piles.

Barbara is taking a day off work to run errands and get some stuff done around home. She had a pile of mulch dumped in the driveway yesterday. I estimate there’s about 3,058,207 mL of the stuff. Right after the guy left, Colin ran over to the pile, sniffed it, grabbed a mouthful, and ate it.

07:30 – I’m still cranking away on the group of lab sessions on revealing latent fingerprints. Speaking of which, here’s an interesting factoid for Trivial Pursuit: humans and the other great apes are the only creatures that have fingerprints, with one exception. If an Australian cop finds a victim who’s been beaten to death with a eucalyptus club that’s covered in fingerprints, he’d first look for suspects among the local gang of koalas, who are the only creatures other than Hominidae who possess fingerprints. Also, of course, koalas are known for their nasty tempers.


15:10 – I just got this from O’Reilly.

09:06 – Thirty days and counting to the deadline on the forensics book. As always, we’ll make the deadline, but we’ll be using every minute available before then to get the book ready to roll.

I finished work on the glass and plastic analysis group of lab sessions yesterday, and I’m well into the group on revealing latent fingerprints. I am going to drop one of the lab sessions that covers developing latent prints with silver nitrate. When I wrote the original draft, silver nitrate was selling for $0.70 to $0.80 per gram. Right now, it’s more like $3.50 to $4.00 per gram, and who knows where it’ll be a year or two from now. Given the amount needed, that’s simply too expensive to include in a kit. It’d be one thing if it was really needed, but silver nitrate development of latent prints is similar enough to other development methods that it’s an easy decision to leave it out.


13:30 – I just ordered 100 grams of ninhydrin crystals for $70. That’s enough ninhydrin to make up 15 to 20 liters of working solution, which is probably a year’s supply for a typical forensics lab, and enough for 150 or more forensics kits.
