Exactly.
Years ago (when I was a teen) living in Hialeah in the 305, one of my brothers, a couple of friends and I rolled up to a 7/11 to get some grub, and there was a dude beating up a female.
We got involved, and the chick called the cops. When the cops got there, the chick told the po-po that we had jumped the guy, and that he was her boyfriend. Only thing that kept us from being arrested was a couple of eyewitnesses that stepped up and told the truth.
After that, I learned my lesson to only act when absolutely necessary. For example, if I see a dude trying to rape a woman, I’m beating his ***. But when it comes to domestic disputes, I would think twice before getting involved.
