Well they told everyone if you have any problems just call George and they did not put a time limit on those calls so it appears he wore the hat 24/7 according to them.
I was addressing your point that SPD might have relied on GZ's statement to conclude that he was on patrol. In that case, GZ's credibility would be at issue and the counter-argument would be that if he lied to the police about everything else, he would lie to them about being on patrol.
I know what you're getting at about the 24/7 thing, but I don't think that's as strong an argument against the HOA as one where they made a statement to the SPD that GZ was on patrol that night. Especially since he wasn't responding to a call and was, possibly, headed out of the complex on a personal errand. I also think it's an argument separate from those based on entirely on statements made by GZ and the SPD. Whether or not a particular action taken by GZ was in his neighborhood watch capacity or his personal capacity would be a centerpiece of the entire case against the HOA I imagine, and would almost certainly be a question of fact for the jury based on all of the circumstances.
But, this is all a little O/T, I think. And probably becoming annoying to others at this point lol
