This is the kind of exaggeration I’m talking about. Nothing about this particular incident as described says to me that the OP calls the police on a regular basis, or even occasionally. Then you go here (with my bolding added):
Having that expectation might—and I do say might—be a bridge too far. But that is a different thing from calling a non-emergency number, explaining what you’re seeing, and letting the police themselves make a determination about whether or not they needed to act. If the OP had insisted the police had come out (particularly if it had been after the police had stated it wasn’t warranted), then I might be more inclined to agree with you. But none of that appears to have taken place here. The OP (as far as I’m reading) reported an observation and left it up to the judgment of law enforcement. It may not have been necessary here if more interaction had taken place with the individual first. But it’s OK to ask law enforcement to make their own professional assessment of the situation, too.
Also, this:
is just factually incorrect. But yes, it you do it frequently AND it is frequently unwarranted, you’re going to have a problem at some point. There’s nothing in the OP to suggest anything approaching that.
