You keep posing false dichotomies. This one seems to be a favourite, where the only alternatives for the police are to do nothing or storm the place with guns drawn.So once again we are back to the question none of you cop haters can answer: What if this was a burglar and the cops just left because the person inside your house didn't respond to them and it was a burglar that stole $10,000 of your cash and belongings and they did nothing?
I suppose if you're a hammer every problem looks like a nail. No doubt you're itching to hammer a nail.
But those aren't the only options. A simple third option was demonstrated just a little too late ie, check with the neighbours. There were also other options. Knock repeatedly, much louder, for one.
Still, I suppose those wouldn't have satisfied your lust for authoritarianism.
Oh well.
