A fight in the bushes and a man calling for help......hmmmmm  and you think the police had no reason to question someone in the vicinity? If you are getting assaulted and I hear the assault going on and the police question me I will be sure to tell them to not bother me and you can continue to be beat up. Then I will continue on my way in the general public with my heroin induced drug addled mind with my can of bear spray, maybe hang out at the nearby school bus stop for a bit and converse with your children.
