Yes, some people here do, including one who is not from the US and justifiably doesn't see the world the same. Yet most of the people here understand THIS tactic, while still being able to differentiate between unjust shootings, and proper response to a shooting call.
If police are following the shoot first ask questions later, then how are those shootings unjust?
Meanwhile, on your point about how the police should respond to anonymous claims... they are not mind readers. And the minute they do not respond seriously to an anonymous tip (something police depts have been promoting for 4 generations now, BTW) and it turns out to be serious and lives were lost because of their slow response they will be accused of negligence.
Why are you framing this as an all or nothing response? I did not say the police should not respond when the call is anonymous. Did you mistake me for someone else?
