Thats why i think that all swat teams should have head cameras so there can be no doubt if the shooting is justified or not. And since they did not have them anything could have gotten down he could have tried to shoot at them and they shot back (71 times lol) they could have been just trigger happy and gunned him down convinced he is a drug dealer and deserves it, ands that they are nov trying to cover up their mistake anyway they can.
Well yea the best strategic play would be to wait for him to leave the house and arrest him then search the house but not everybody is a strategist
Dont the police usualy scream tis is the police get on the ground now blabla bla ...., and they do this so people know that its the police pointing guns at them and entering their houses not some mugger.
