Apparently Phoenix and his other super hero members call 911 if they see something going down, then intervene with force. They've come to the rescue of hundreds of would be victims and often restrain the offender until the police arrive.
He does need to protect himself and has been injured in his efforts several times. It seems as if this is just part of the job though and nothing deters him. He carries with him a Tazer, net-gun, and grappling hook. I really wish I could hang out with this guy. Check out the video.
