Let’s say GZ was convinced that TM was a threat to the neighborhood, which he must have been to make a call to the police. That was his mindset, a suspicious stranger in the neighborhood, looking around with his face concealed in the rain. The guy disappears.........so GM had two options, try to keep him in his sights for when the police arrived or get in his car, go on to the store and allow what he believed to be a danger to the community roam the streets. Next morning....an entire family is found dead in a ransacked home. As for Don West’s opening knock knock joke, I finally get it.
He'd be the first to say that he wasn't convinced, he was suspicious, and thought it warranted being checked out. Not a safe neighborhood, if you look at the statistics. Lots of burglary, one hot burglary in the past months.
