That's what non emergent lines are for, there is no emergency in any of those types of crimes. It is also clear neighborhood degradation if crack and meth dealers, pimps and their hookers and general douchenozzles are operating unchecked.

The prick on the phone last night asked more than once if I needed an officer to respond to my location. No, A-hole....I did not call 911.

But yes, you people need to be aware of this stuff. Drug deals go bad, sex deals go bad, and pissed off competition (read gang rival here) can cause problems as well.
