It's one thing to fuck up. It's another thing not to address the fuck up and continue fucking up, one raid after another. Their methods need to be changed. The laws need to be changed. There is a resolution for this problem. It's not just a single fuck up.
Yep, it's far beyond a single fuckup at this point. In a country with a right to self defence, if cops don't identify themselves this will happen over and over again, and it will not be the home owners fault.
