It's unfortunately common, and most PD's also don't have any way or system in place for you to inform them that this is likely to happen ahead of time. In fact there are people who get SWAT'd multiple times a week, and the PD shows up every time all gung ho. In one case I know of, the police started threatening to charge the victim for all the false calls.
But yeah. Someone can just call the police on you and they come and arrest you.
