I've shared this story before, so apologies to those who have already heard it. I'm a solid supporter of the 2nd but also in the "something needs to be done but I don't know what" camp.
Long story short, I had an employee attempt suicide and spend a couple weeks in a mental health facility. He was released on a Saturday and came to work the following Monday. He came in and provided me with is "return to work" release form, etc.
While on his lunch break, he purchased a handgun at a local store, came back to work and was showing everyone pictures of it, was telling them that it was in his car "but I can bring it in if anyone wants to see it"
Obviously this freaked everyone out, and I had the cops come And escort him off the premises.
So, again I don't know what the solution is but it seems like someone 5hst was released from a mental health facility 48 hours prior should be able to purchase a firearm.
Apples to oranges comparison- 15 minutes to buy a gun, 6 weeks to close on a mortgage
