or at least warm. As per the Globe’s Metro Desk, Boston police have a new gizmo to link perps with pieces:
When the Bullard TI Commander camera is pointed at a recently discarded handgun, the body heat retained by the gun can be seen, prosecutors said. This can be used to confirm an officer’s observation that a suspect had just discarded the gun and rebut a claim that the gun had just been lying there.
But just taking pictures isn’t enough . . .
After Boston Police purchased the camera several years ago, prosecutors reached out to experts at MIT and went through a series of legal steps to get Pillai and Wahab, who both have master’s degrees, qualified as expert witnesses.
Suffolk District Attorney Daniel F. Conley said the two students had put a “powerful tool” in the prosecutors’ toolbox.
Commenters are not that easily impressed.
This is completely pointless, all it shows is that a gun was “handled” by someone, which could be either the criminal or the victim.
Basically, this is used to intimidate suspects into confessing, given that they don’t understand that the forensic claims of this technique are lies. As was pointed out above, even if you take the thermal image at face value as showing the gun above ambient, you still need to link that thermal energy to the suspect. If you do that by the cop claiming he saw the perp toss the gun, then you did not need the thermal image. If you do that by finger prints found on the gun, then you did not need the thermal image.
But what if no one actually saw him toss the gun, but he was the only guy in the vicinity?
