I'd take it one step further:

I live in a medium to medium class neighborhood with a few lower priced apartments dotted throughout. One is actually next door to me. I had to call 911 last weekend when a bbq at the apt building next to me was close to violence. I listened through an open window as one calm male tried to disuade his friend from starting a fight as the latter ranted for 45 minutes in the street sometime after midnight. I heard male number one mention an open arrest warrant as an attempt to reason with male number two that violence was not going to end well. Male number two repeatedly dismissed this and periodically became hysterical with anger.

Between my initial call to 911 and the time when police arrived, I heard a new voice arrive, alerting the hostile guy that he (male number three) had called his cousin for backup and reminding everyone that his cousin is a Crip (a west coast gang, for those who are unfamiliar). I made a second 911 call to update the officers that the situation appeared to be escalating.

So, what I'm driving towards is the additional possibility that this type of behavior sticks out terribly in a quiet neighborhood where most residents have families and go to sleep by 10pm. The likelihood of someone notifying authorities is probably greater than in a high crime area because this is an extremely rare occurrence here.

Edit: yes, I live in a predominantly white neighborhood and the bbq attendees were all black, but that seemed less relevant until I remembered that someone is likely to ask.

This is exactly what I was talking about in my post above.

The instinct or intuition to notice danger is totally different. Call it paranoia, call it introspection, it doesn't matter, it is there and it is real.

This is why the recent migration from MENA to Germany is going to go very wrong. Combining Germans, a people notoriously for being 'societal correct' with young men from MENA is perfectly calibrated to result in violence. There are no two ways about it.
