An absence of a documented history of violence doesn't proof that a person made bad life choices.
So this begs the question:
If the homeowner here has absolutely NO history of violence, why would they raid his home in the same manner, with the same tactics they would raid the compound of a mass murdering international terrorist?
They raided it in this manor because they are a bunch of Delta Force, Navy SEAL wannabes who think they are at war with the citizenry in the same way were at war with Al Queda
Are you for real? Seriously?
