There were TWO houses and they failed to find out which one was the one to hit.
That should have been clarified or the raid called off/postponed until they knew which one it was.
There is no call for "flip a coin' cop work in this case.
They roughed up the wrong people, likely tipped off their target, and compromised the informant (if the target has squat for brains) as well.
Real friggin' genius, and frankly inexcusable.
This foulup was preventable. Someone did not do their homework.
I am no fan of dynamic entry because a little slop in the paperwork and someone busts down my door, I will shoot first and ask questions later, assuming that anyone breaking into my house does so with malicious intent.
Then what?
