Besides telling them they can’t practice, what can you do? It appears Adam Lanza didn’t do anything on the range to warrant getting kicked off of it - let alone committed. The range makes you safer with your weapon, and it also increases your capability with your weapon. I don’t like the idea of arbitrarily restricting it.
Lanza had gone to a Dick’s Sporting Goods recently to purchase a rifle, and he declined to make the purchase when told that he would have to undergo a background check. That’s a point where I would be willing to say that someone should be reported to law enforcement for further investigation. I’d rather have someone attempt to make the purchase and fail the check than decline to purchase because of the requirement for a check.
It’s like here in Volusia County, Florida, the Sheriff (Vogel) once set up signs on I-95 on the northbound lanes saying “Drug Interdiction Stop Ahead - Be prepared to stop.” Then he parked deputies on the other side of the highway and stopped people who turned around in the median. They caught lots of people with drugs that way until some judge ordered that the signs were unconstitutional.
What we don’t know and my never really know is just how badly this guy had turned in recent weeks or months. I would venture a guess that his mother knew that something had changed with him. His brother said that he hadn’t been in contact with Adam since 2010. Why? What happened in 2010 that caused a break in that relationship? Was the mother trying to keep the plates spinning and protect Adam’s reputation and her own rather than working with appropriate mental health counselors to protect everyone else from Adam? If anything like that was true, and she kept guns and ammunition where he could get to them, then she made a major mistake.
I think that happens in the vast majority of cases where there is a severely disturbed individual. Rather than acknowledge it and do something about it, which could be a source of embarrassment for the family, they just ignore it and try to pretend that it will sort itself out.
May be requiring “references” to practice routinely can help? In this case, all his references would have pointed to an aloof sociopath.
