This is tragic but occurs often across the nation.
Orlando Florida had a event at a downtown range called Oak Ridge Gun Range about 7/8 days ago.
I also read a brief media item that a guy shot himself at the recent NRA 500 NASCAR event.
Anyone in the shooting sports industry or who works around firearms should be alert to any EDPs(emotional disturbed people).
I know $$$ is important but you may see someone who is intoxicated or unstable.
I've been in gun shops before with customers who were clearly drunk & holding firearms.
Thankfully the weapons were unloaded.
The staff & sales clerks should have keyed into that.
