How safe do you feel?

I have been noticing with more and more concern the increasing amount of what looks to me as VERY young police officers on the streets carry what look to me like AF-47, (I don’t know much about guns!!!). When I have seen what feel to me like “gangs” of them on street corners I have honestly asked myself if I feel more or less comfortable. Fact is they make me nervous as hell, and part of me has been comforted by the fact that I figured that probably most of the guns are none functional or not loaded. I came across a video yesterday that confirmed that I should be very afraid, AND that my hope that the guns are not loaded or not working was crushed.. indeed they are loaded, they do work, and unfortunately looks like the police are somewhat lacking in their training.
