We don't know that they didn't try to talk to him and deescalate at the beginning. The videos start from the middle of the tragic
situation. By the time the videos are recording, things were going downhill fast.
But it is easy for us to look backwards and say 'maybe' the wife should have been allowed to come closer to the armed suspect.' ---then again, they don't know what their domestic situation was like. Would she trigger things in a bad way? Would he shoot her? They would really be in trouble if something like that happened.
When cops try to detain someone, and there is a weapon involved, and an ex-con is facing serious time because of it, things are volatile and dangerous. The cops are very concerned for their lives too because these are the situations that get them and their partners and possibly bystanders, killed or injured.
Everyone is now talking about how the cops should have looked out for the victim, and should have 'saved' his life, and protected him from himself.
But they gave him a dozen or more opportunities to drop that weapon. He had many chances to end the whole nightmare himself. His own wife was screaming at him, begging him not to do what she saw him about to do. And yet, the public wants to fault the officers.
Here was an ex con, sitting at a school bus stop, waiting for his son. And he is rolling a joint, about to get high, while armed with a loaded weapon. And everyone is calling out the cops as the ones to blame for this mans sad death. No mention of the very poor choices the guy himself made that led directly to his death.
