The chance of an older guy doing a mass shooting is very low - the rate of anyone doing it is already very low - for older people, even lower. So don’t get worked up about that fear just because its in the news.
If he trusts you, and you want to talk to him, you can politely tell him to take it easy on “weaker” people than him.
Otherwise, avoid him.
The point of my post is that this red flag law doesn’t work - Even when the situation calls for it.
If anyone here supports this, this is what this means.
