Yes; That is what the article says. It was an HOA thing. Not a city ordinance. Real world is that HOAs are mini-governments. But let's suppose it was a city ordinance; does that warrant killing someone for not cutting their grass? I know the article states he started shooting because people were trespassing on his property because a city or HOA ordinance required the grass be cut. In his view were there trespassers on his property? Most likely. Talk about the big machine not being able to de-escalate.
