But they get to choose what they do when they get there.
Au contraire! How many times has it been pointed out they are NOT obligated to respond to any specific call, if at all?
“They don’t get to pick and choose which calls they respond to.”
Exactly. Now how they act when they DO respond (and respond they will, because they must - its their job) - well, that’s another matter. But be careful of provoking officers when they do respond, because it is both a stupid and dangerous thing to do, and it also does not help our case.
IMHO, anyone who is swatted like this needs to act with the utmost of care and respect, being fully in compliance with the officers. Once they have figured out what happened, and that you are no threat to anyone, politely ask them to investigate and/or arrest the person who called it in. It won’t happen the first time, but if that happens 5 or 10 times and the story gets into the papers/internet, then a lot of pressure will be brought to bear to prosecute this animals for filing false reports and wasting scarce police resources.
