I grew up in a pretty poor area in CA. Many people I knew then were in gangs. Some are dead, some are paralyzed ect. Violence is a cycle.
Here is a sick sad story of a friend of mine.
Her brothers were drug dealers. House got shot at multiple times. One of her sisters was convinced at 14 to sleep with the brothers when she was 14. Mom could not care less about what is going on. My friend started dating her brothers friends at the age of 14 when the guys were all 20+. She could only date her brothers friends because they would not let her date anyone else. She got tired of her brothers and started dating a guy who was 30 when she was 17. Got married to him just so she could move out of the house. Is now split from him and is a HS dropout. No future, no hope.
Her situation is not biological, its cultural. Sad.
Man, that's pretty messed up. Poverty in Tennessee is much nicer. Well, when I was a kid anyway, maybe not now.
I'm just taking a wild guess here, but I don't think many cops listen to rap music.
<sigh>
1. Gangsta rap with its lyrics praising killing cops is played preferentially in a lot of bad neighborhoods.
2. When cops hear this music - regardless of whether they personally listen to rap - it probably reinforces in their minds the concept that they are surrounded by people who want to kill them.
3. If so, then cops are more likely to use deadly force more quickly and less likely to give anyone the benefit of the doubt, because subconsciously they have already judged the people as likely cop killers.
I really don't think that was a difficult concept to follow.
