There is a trend in the U.S. to NOT call the police, especially in cases of mental illness. (People in a mental crisis are 4X more likely than average people to be killed by the police.) My experience is that when you do call the police, they assume the person who called is the problem. Only if you're smart (and lucky) you might direct them to the real problem. I quit calling the police when one of them responded to my door and asked me to go back in the house and come out with a gun in my hand. I told him I wasn't that stupid, and his partner emerged from behind my truck aiming a pistol at me. That finally convinced me to quit asking the police to, "serve and protect" me (somewhere around 1985).It's always up to the population itself, and not to its government, to take steps in defending itself against abuse.
A new method called Cell411 calls local residents to the scene, not the police. The police have learned about this and sometimes place Cell411 calls so they can harass any citizens who do respond. So, the people devise ways to avoid the police, but the Surveillance State tries to defeat that.

and the police take on how to use it:
Step 1: Download Cell 411 from your Google Play or iTunes store.
Step 2: Go to a low traffic area of your beat.
Step 3: Set Cell 411 to Patrol Mode and then initiate a fake police event, such as a traffic stop or arrest.
Step 4: Get your ticket-book ready, and conduct a traffic emphasis patrol in the area.
