Deanimator- You obviously have some issues.
Again, I repeat, the screw-up on the address was bad and should not have happened. But I can't fault the agents at the door for using methods that are defensive. They have families, too, and want to go home at the end of the day.
As for your asking me how being rude better protected them, that's perception. They were in a defensive mode, controlling the situation. You see that as being rude. I see it as doing their job. They see it as staying alive.
You say don't cooperate with cops because you are going to jail. Certainly IF YOU ARE THE SUBJECT OF THEIR VISIT then that's good advice. Shut up, demand to see the warrant and ask for an attorney IF THEY CAME FOR YOU. That's not the case, here. If the cops (any cops) come to your door looking for criminals who aren't there how do you jeopardize yourself by helping them? I want to set them straight and get them on their way ASAP and stonewalling, refusing to cooperate with info, or copping a tough guy attitude ain't gonna get that done. What's the point to getting your panties in a bunch? It was a goof. Cops are human, too. If they are curt it's because they are aprehensive. Remain calm. Politely tell them they have the wrong house and send them on their way.
I can recall having cops draw their guns on me twice. Once I accidentally set off the alarm at work. I was alone in the warehouse at 5 am. The silent alarm brought two uniforms to the scene who surprised me as I was loading my truck for deliveries. I calmly explained that I was an employee, gave them my ID, showed them my time card with my name printed on it, and showed them I had a key to the door. They relaxed, apologized for any stress I had experienced, and left. I told them I understood they were just doing their job.
The other time I was pulled over because I was driving a red pick up truck and wearing a blue denim coat. A store had been robbed a few blocks away by a man fitting that description. As I spoke with the officer he got a radio call saying the actual suspect had been captured a mile away by another unit. Apologies all around and again, I understood that's his job.
These cops thought they might have been dealing with dangerous criminals. I can't blame them for drawing their guns and taking appropriate measuures to defend themselves. I think you ask to much if you expect cops to approach suspects with flowers and candy in their hands. If cops were required to behave as you expect I think you wouldn't have many applicants for the job.
