#22I am the author of the referenced article. The problem is matching surveillance camera images (like from Lord & Taylor's) is impossible because of the steep down tilt angle of the cameras plus their low resolution. Smartphone images could be a little better as the angle is more head on and the resolution is higher. However, even those images tended to be in a wide field of view which means low pixel density, hurting…

#23In the end it was mostly dumb luck, dumb criminals, and the fact the poor victim who lost their legs managed to survive. In fact that was the success, that more wounded people didn't die thanks to fantastic work by the hospital and doctors.
Instead of patting law enforcement on their backs, how about thanking the doctors, where is their applause?

Matching surveillance camera images is always possible no matter how bad the image quality is. The only matter is how many false positives show up. Facial recognition algorithms always give their best matching candidates, with thresholds to skip those not quite matching ones. Your article makes it sound like no such results were produced at all, which is unlikely how recognition is supposed to work.

#25Not just facial recognition, the "terror watch list" failed (after a warning from Russia about the older brother) lack of background checks on the AR15s they owned failed, the secured perimeter failed (the teenager was outside of it) the city lockdown failed (the guy smoking the cigarette outside when he saw the blood was technically violating the lockdown). In the end it was mostly dumb luck, dumb criminals, and the…
But yes, multiple subsystems failed in the police response. If you listened to police scanners, you also heard that they had some trouble identifying streets correctly, or keeping their mics off when not talking. But police response protocols are one human system that definitely needs to be able to work in the face of multiple subsystem failure. I say judge the police on how the response worked as a whole.
I have to say though, thank god that Dunkin' Doughnuts' Tactical Ration Deployment Vehicle ran smoothly.

I believe the curfew had been lifted moments before he went outside for a cigarette - at least that's what's been reported over and over and over.

Actually, the lockdown was voluntary, though with strong community pressure to comply. But yes, multiple subsystems failed in the police response. If you listened to police scanners, you also heard that they had some trouble identifying streets correctly, or keeping their mics off when not talking.

But for the shelter-in-place order (it wasn't a lockdown or curfew) the guy may not have been home in the first place for find Tsarnaev.
