About twenty years ago, I had an upstairs neighbor who was very obviously beating his wife/girlfriend. You could literally hear her begging him not to hit her.
I called the cops on him several times before he climbed out on a fourth floor ledge threatening to jump. He kicked a cop who tried to pull him in... an error in judgment on his part. The last time I saw him, he was handcuffed in the back of a squad car, beating his head against the side glass, a la "Cops".
What would you have recommended I do instead? Go upstairs and fistfight with him? Shoot him?
What was he going to call the police on me FOR? NOT beating my girlfriend?
If police have ANY use, it's in situations like that described above. If not, they need to be abolished completely.
