Just know this guys: Special Weapons and Tactics teams have a certain set of rules and guidelines, rules of engagement, ect. that they MUST follow when putting a house under siege, that could house potentially dangerous armed criminals. The men here were just doing their jobs. The fault here lies with the people who sent these men to the wrong house. The SWAT team does not collect intel on a house before they raid it. That is above their paygrade.
Also, why the hell do we only hear about the stories where cops forget up? What about stories where cops successfully do their job: protecting the innocent and maintaining order? Guess that's too boring.
