Most places didn't even have high rises, first of all, and the 70s killings happened before they were populated.
Explain LA, DC, and places like Kansas city where most of the killings happened outside of detached single family homes, row houses, and 2 story standard apts?
They were populated in the 70s because thats where a lot of the migrants moved into looking for work in the cities.
And as for your second question I'll cut straight to the chase. Any place you have black and disenfranchised black people living together, they're going to kill one another. All nationalities are somewhat subject to this.
When you move people away from one another, lock them up, or they die from the violence, the murder rate goes down. Thats until another generation picks up the tradition. On your own, look up the murder rate from 50 years ago and parallel it with the population rate.
example: Washington D.C:
| Year | Total | black |
|---|---|---|
| 1980 | 638,333 | 448,229 |
| 1990 | 606,900 | 399,604 |
| 2000 | 572,059 | 343,312 |
| 2010 | 601,723 | 305,125 |
Same rings true for Los Angeles. Look them up, I don't have to post them numbers because you know blacks not growing in these cities.
