Having no knowledge of the time of the incident, I can’t help but wonder. Was it at night? Some areas of Temecula are rural. Was the homeowner plagued by break-ins? Had he been threatened in the recent past? Illegals using his neighborhood as a pathway?
While I am sure it was disconcerting to the minor and to her (at least I think it was a her. One can never tell for sure anymore) father, I cannot help but question the necessity of the physical arrest.
This address is inside an urban gated community.
Don't know a whole lot of answers to the obvious questions, but some yes... Gated community of multi-unit condos - so likely relatively crime free area with high levels of local traffic, but probably very unlikely for someone to randomly knock on your door at any time.
If the father had any sense, he would have handled the entire thing differently. Unless the homeowner was clearly off his nut, the father should have explained gun rights and property rights to the girl and amended his approach to knocking on strangers' doors. If the father had not become so outraged at the sight of the gun, he might have made a friend.
The homeowner could have had reason to be suspicious. These days, you do not know whom to trust. People impersonate utility workers, police, pregnant women and also use children as bait in order to commit crimes.
