I live on the south side of Chicago. Whenever I pass through "trouble" intersections (near the El, etc), I see a myriad of tech perched atop towers--red light cameras, gun shot detectors, CCTV cameras, etc. Adding a small "hut" to contain UAVs is the logical next step. And it will do nothing to fix the root cause of the issues. Neither will hiring more cops to patrol distressed areas. The problem is cultural.
