So to be clear : In the US the government (or its representatives) can damage your property, and then isn't paying for those damages without hassle for the owner ?

Besides that : Why does the police need to use this amount of force to apprehend someone with a gun ? Couldn't they just isolate the guy, and cordon off the area so he can't harm others and then just wait ? Unless there are hostages involved, or immediate danger to the public, it seems a more appropriate way is to de-escalate rather then escalate.
