If they think a mistake was made with the warrant they shouldn't execute it. Duh.
They dont know a mistake is made until AFTER it's been served. Duh. Those are thankfully quite uncommon, but do happen. For example, especially on drug warrants. A snitch says "Joe Blow" lives at the white house on Main Street, 5th one on the right. And drives the cops there and points to it. Unfortunately, Joe Blow was drunk and high when he was at the house party, and the correct house is actually the white house, on Main, 5th one on the RIGHT.
Warrant was issued. Cops have all reason to believe it is right. Wrong house. They find out once inside, and it's a soccer mom and 55 year old husband. Damn. Nobody is hurt thank goodness. PD should pay for the families busted door and kiss some major ass to apologize, then take away Joe Blow's plea deal.
But you still dont want bullets flying. We aren't Mexico. If the cops show up, there is a 99.999999% chance they are there in good faith, and if you cooperate, and they are wrong, you'll come out fine, especially if it is just the wrong house. If you are committing a crime, but they didn't do the warrant right, you'll likely get off at court. Bullets are never the answer.
Until now, obviously, since these politicians decided to give residents the right to make that choice.
