"If they didn't feel as though they were getting control of him before he could get control of whatever that was in his pocket. Tasing may have been appropriate," said Crivello.
Crivello said he could not see what was happening during the struggle with Brown after an officer asked him to take his hands out of his pockets. That was right before Brown was taken to the ground and tased.
He also suggested this could have been prevented if officers always worked with a partner.
That's something the MPD Chief Alfonso Morales said he's focused on.
"We have worked exhaustively in the last three months to really try to figure out how we are going to handle this situation and move forward from it," said Morales.
The Milwaukee police chief finally answered some questions about the video Wednesday, but still is not saying much.
Morales has known this moment was coming when he and his department would be responding to the tasing and handcuffing of Brown.
"We're really working at putting our officers back at the district. We're looking at community-oriented policing," said Morales.
The chief is backing up his apology with a promise that officers will get new instructions on how to handle themselves with the public.
"Absolutely retraining, but here's the biggest and one of the things I brought up when I was campaigning for this position is leadership. This is leadership and that's what we're focusing on and changing our department," said Morales.
