Arizona Police Deny Excessive Force Used in Incident Caught on Tape

Video posted on YouTube

Mesa police considered the recent arrest of an uncooperative man outside a convenience store a life-threatening incident after an officer was punched in the face and a second officer's gun was flung to the pavement nearby.

But a bystander using a cellphone recorded a video and posted it this weekend on YouTube, accusing police officers of excessive force and forcing them to defend their actions.
