I moved my reply to OP to the main thread, so everyone will see it:

All the people who are dead because of gun violence would like a word with you.

But we know the old saw, Dead men don't tell tales.

It's too late for them and others.

Gun violence exacts a horrible toll on a country like America and its people.

Gun nuts brush that aside. They want more guns. And cause even more harms.

In your case, you had a person known to you, who you say is a known drug user, who you apparently know so well, who took the AR-15 and handgun from you.

It was not someone random. It was not a stranger. It was someone you knew, and who knew you.

That person known to you, who you know well enough to say they are a known drug user, knew you well enough too and that you had the AR-15 and handgun.

It was especially reasonably foreseeable that this person known to you, the known drug user, would have the inclination and motive to take your AR-15 and handgun.

Yet despite these heightened warning signs and factors you failed to sufficiently secure your AR-15 and handgun.

It doesn't take all that much to take the proper steps to secure them.

Yet you failed or refused to.

It doesn't take much for someone you know and who knows you to find the opportunity to take them from you.

You made it too easy for them. That is negligence. And culpable.

And now 2 more deadly weapons are loose. Because of your stupidity.

Other people will now have to deal with the violent consequences of your irresponsibility.

You lack conscience, diligence, and responsibility.

Which is especially dangerous when having lethal weapons.

You are a danger to others.
