Chicago Robber Caught By Facial Recognition Sentenced To 22 Years

mpicpp (3454017) writes with this excerpt from Ars: "The first man to be arrested in Chicago based on facial recognition analysis was sentenced last week to 22 years in prison for armed robbery. ... In February 2013, Pierre Martin robbed a man at gunpoint while on a Chicago Transit Authority (CTA) train. After taking the man's phone, Martin jumped off the train. However, his image was captured by CTA surveillance cameras and was then compared to the Chicago Police Department's database of 4.5 million criminal booking images. Martin, who already had priors, had a mugshot in the database. He was later positively identified by witnesses. At trial, Martin also admitted to committing a similar robbery also on the Pink Line in January 2013—his face was captured during both robberies."

    Shoulda just hacked the Chicago camera system with his phone.

    This is nothing more than the type of fingerprint matching that's been going on for many decades. It just puts a name to a person after the fact. Now on the other hand, if he was actively recognized via facial recognition as he was out and about in public and then apprehended, well that would be a different story.

      I agree, but I think there's another concern here as well: false positives are significantly more dangerous than with other fingerprinting techniques. If DNA samples or fingerprints provide false positives, we have (admittedly error-prone) eyewitnesses as a final layer of defense, and since people who look entirely different can have similar fingerprints or DNA signatures, it's likely that the people look nothing alike. Not so with facial recognition, since a false positive is likely to be close enough to a true positive that it will be incorrectly affirmed by eyewitnesses, even if the authorities don't bias them by telling them that the guy was a match.

      None of which is to say that I think we should stop using it, since it is a valuable tool. I merely think that it needs to be used with an understanding of its faults and taken with the grain of salt it deserves.

      Spell it out for me then, because I'm clearly not getting it.

      Near as I can tell, they need to be able to demonstrate in court that they have a way of linking the guy in the train footage to the person they've apprehended. There may be a few links in the chain tying the person to the crime. If the police claim it's via facial recognition from the train footage, they'll need to be able to demonstrate that they can make that identification from the train footage. If CCTV footage gets involved, we've added an extra link to the chain, so they'll need to demonstrate that they can tie the person from the train footage to the CCTV footage (e.g. the person is seen heading in the same direction wearing the same clothes at the same time and location) and then can tie the CCTV footage to the mugshot, otherwise it'll do them no good. And if they're doing that, I don't see why anyone should have any issues with it, since it's no different than going to neighboring stores after a robbery to see if any of them have cameras that got a better view of the suspect's face. That's old-fashioned detective work, not something to fear.

      On the other hand, if all they're doing is matching CCTV footage against mugshots, without linking it back to the train footage, then they've failed to tie anyone to anything at all. All they can get from that is "previously arrested person X is currently at location Y", which wouldn't do them much good in court, and it wouldn't be useful to them in the least in getting a conviction since they wouldn't be able to demonstrate the link back to the suspect from the train footage.

      And that's before we even begin to address your claims about the NSA stuff, which I find highly unlikely, even with the revelations we've had (everyone knows it's the FBI that keeps the database on US citizens, not the NSA :P).

    Chicago Robber Identified By Facial Recognition Sentenced To 22 Years

    Caught would imply that he was walking down the street and facial recognition directed authorities to him. That did not happen.

      Wow, somebody being arrested for an actual crime that the suspect actually committed is a "police state"? In a public place it is best to assume someone is always recording so don't commit a crime.

    Any remotely competent lawyer would get that kind of identification thrown out of court. Any lineup, even a photo lineup, without multiple options is inadmissible in court.

    Sounds to me like this was used as an investigative lead that helped them find other evidence, rather than as the principal evidence presented in court. This really isn't different than a police officer viewing the recording to see the offender's face, then going through books of mugshots to find the face, then investigating those people that the officer thinks might be the offender. This is simply the computer taking the image that the police officer identified and searching those "books" for close matches, then the police looking at the MO of the crime as compared to the MO of the person previously arrested, and investigating ones that have the most commonality first.

    In this case they identified a suspect, the suspect apparently had offended in this same way before, and the suspect was tried and convicted. This doesn't seem to violate any new privacy considerations- the recordings being collected themselves are nothing new, and the mugshot database isn't either. Simply making the comparison itself doesn't add any new fuel to the fire of personal liberty complaints or of violation of privacy.

    Maybe he deserved this, sounds like it.

    But it doesn't justify the mass surveillance being put in all over our public spaces. It can't even be justified on the cost, but far worse is the erosion of your freedom to go about your business without being tracked and monitored permanently. It might catch the odd transgressor, but that is not an acceptable enough reason to piss away all our privacy.

    Oh but you have nothing to hide, so what? Well, it was Joseph Goebbels who first made that pithy remark about having nothing to fear, and look where that ended up - many perfectly innocent people had everything to fear.

    The only reasonable response to mass CCTV is for everyone to wear a balaclava. Once the system is rendered useless, they might reconsider spending taxpayer's money on it. And it sends a strong message that we simply don't want to be tracked, even if we are not criminals.
