They didn't see that, though. They saw a kid with a bulge over their pants pocket, suggesting that something was in the pocket. The idea that any kind of algorithm can accurately predict that an amorphous pocket bulge is a gun is just bonkers stupid.

(Ok, ok, with thin, skin-tight, light-colored pants, maybe -- maybe -- it could work. But if it mistook a crumpled-up Doritos bag as a gun, clearly that was not the case here.)
