Why forensic science is failing us — and why tonight's NOVA documentary doesn't quite cut it

In 2009, the National Academies of Science published a massive report on forensics. For many Americans, forensics is possibly the most familiar of all the sciences. It's the one we welcome into our living rooms every night, along with TV crime dramas and murder mysteries. But the report's conclusions might surprise you.

For one thing, it's hard to even generalize about the state of forensic science in the United States, because everything from standard practices to accreditation varies widely by sub-discipline, law-enforcement agency, and whether the law enforcement is happening at a local, state, or federal level. Worse, it's not at all clear that some of those sub-disciplines have a sound, scientific basis. For instance, DNA analysis tends to be pretty well-supported by evidence, while fingerprint analysis remains an art, more dependent on the person looking at the fingerprint than on hard laws of anatomy. Of course, the report also found that there simply hasn't been enough research done to determine how scientific most disciplines of forensic science are to begin with. Meanwhile, the Supreme Court has allowed trial judges to certify forensic techniques as reliable even though we don't know whether they they are or not — and those decisions have been made in a haphazard, inconsistent way from one judge to the next.

Given how much our legal system relies on this stuff, we should all be feeling more than a little uncomfortable right about now. The state of forensic science, combined with its importance, virtually guarantees that there are innocent people behind bars (or worse) and criminals on the loose.

Tonight, on PBS, NOVA will premier a documentary on the flaws of forensics and how they might be solved. I liked the show and I think it's definitely worth watching. That said, I think NOVA took an angle on this information that made the show less useful (and less important) than it might have been.

Bones of Turkana: Meave and Richard Leakey on human ancestors and the Leakey legacy

The Leakey family is like the Kennedys, but for paleoanthropology instead of politics. Think about any hominin fossil or artifact you can name.

Join a live Q&A about the first few days of the Fukushima nuclear crisis

Last night, PBS FRONTLINE aired a new documentary about what happened at the Fukushima nuclear power plant during the crucial first days of that crisis. Using amateur video shot during the earthquake and tsunami, interviews with power plant workers who were on the scene, and some astounding footage taken inside the power plant itself, the documentary is extremely powerful. It feels weird to say this, given the effect the meltdowns have had on Japan's energy situation and the lives of the people who lived and worked near the plant ... but it seems as though Fukushima could have been a lot worse. The documentary shows us the valiant risks taken by firemen and plant workers. It also shows us the moments where, in the midst of the Japanese government and utility company TEPCO doing a lot of things very wrong, individuals stepped up to make decisions that saved lives. Without those things, this would have been a very different (and much darker) story.

In about ten minutes, I'm going to be moderating a live Q&A with Dan Edge, the producer of Inside Japan's Nuclear Meltdown. I'll be asking him some questions about the story, and the process of filming a documentary like this. There will also be opportunities for you to ask Edge some questions, as well. (And I already know y'all are good at coming up with interview questions.)

Frontline post-Fukushima documentary "Nuclear Aftershocks" airs tonight

[Video Link]

"Nuclear Aftershocks," the PBS Frontline documentary which Maggie described in a Boing Boing review as "brilliant," airs tonight online and on local PBS stations at 10pm. I've seen an advance copy, and I agree that it's excellent—though I'm admittedly biased, since I love everything Miles O'Brien does, and collaborate with him creatively from time to time. A preview of the documentary is above. They have some cool web extras up at the Frontline site, including a map of how much nuclear power each US state relies on.

Truth and consequences: FRONTLINE's brilliant documentary on Fukushima

Nuclear Aftershocks is a new FRONTLINE documentary, airing tomorrow, January 17, at 10:00 pm Eastern. I watched an advance screener yesterday.
