Wait, so they're supposed to be on all the time (that they are actively patrolling) so that the 2 min buffer exists, but as long as they turn on the cameras immediately before using lethal force it's just fine and really shouldn't count? I mean close to 2 minutes is kinda the minimum here. All they have to do is press the record button sometime before they pull their weapon or at least within a few seconds of discharging it to have 1:55 saved. Otherwise, they can inform their victim/perp that they are going to execute them and then turn the camera on for the few seconds before as a warning to anyone who would challenge them. Is this not a corner case you considered?
