To me, this chick sounds psycho already. She pals up to the biggest, toughest gangs around, first with a gangbanger, then with the cops. She tells big daddy (cops) that another boy (gangbanger) is hurting her. She manipulates one guy to attack another guy. This is like high school folks.
Now, what to gangs form around? Mostly, it's the drug business. Now these guys aren't geniuses, how can they compete with Procter & Gamble in the drug business? They can't. First have the government prohibit some drugs, then leave it up to the most brutal to compete for the illegal business. Voila, you end up with Al Capone or MS-13 or this particular gangbanging lowlife. They can't compete with P&G in drugs, but they sure can compete in violence. And THAT's the history of prohibitions. Prohibitions of anything, there's nothing special about drugs that causes this violence. After WWII, the German's banned coffee, cigarettes and other luxury goods and ended up with the same gang violence.
Jeesh, man, it's basic economics.
So? This wasn't about drugs. It was about a violent gangbanger with guns in the house.
Look. I know you're all excited about no-knocks and wrong houses and drugs. Just be patient and I'm sure that within the next month or two someone will post an article concerning all three (and, we can only hope, a gunned-down dog).
THEN you can get all indignant and self-righteous. Until then, cool your jets.
