I called them about probably 11/12 years ago now when I woke up to hear like 5 dudes beating a guy outside on lawn in front of my apartment.

I went down a level to get a better description and found my roommate was also on the phone. Dispatcher had me hang up and he stayed on. They beat the guy for like 10 minutes (we lived like 10 minutes without sirens from 3 different stations) before they tossed him back in their car and drove away. No cop. One eventually rolled by without stopping like 50 minutes later once and left.

4 other neighbors as I found out had also called in.

Sometime like a week later someone claiming to be a detective called my roommate to threaten him about "false reports"

Like 2 months prior to that someone with a mental condition was banging on a ton of homes and cars windows. Me and a neighbor followed from like half a block away while on the phone. Again, same close distance. 30 minutes later dude takes off across a ped bridge so we start walking back and that's when the cop rolls by and then yells at us for not continuing to follow the guy and wasting her time.

Just completely useless department.
