I called the cops on a vagrant sleeping in my building's parking structure stairwell.

The cops came, nudged him awake, and then waited calmly while his drunk ass gathered his crap and yelled at them as they escorted him down the stairs and away from our building.

LAPD may be brutal to suspected gangbangers and minority drivers but they're overly polite to the homeless to the point of being fairly useless at preventing the homeless from committing crimes (that affect others, like theft or property damage).
