Just because you don't see people and you think the neighbor kids are at school doesn't mean there aren't people around that could be hit by a stray bullet. Maybe even people actively trying to not be seen, though they aren't thieves casing the house or whatever. They are just extremely poor.
I spent nearly six years homeless. I used to see drones above my tent at night when camped at the foot of some bluffs below expensive housing. I don't believe the people in the expensive housing had any idea I was there. I did my best to have tree cover, to come in under cover of darkness and remain quiet and so forth.
I was trying to avoid telling that personal anecdote because I'm routinely given shit for telling my personal anecdotes to explain what I mean.
