Sense Sonnet - Chiller

Gun Check Point

The universal background check,
A sensible gun thing to do.
You want a gun - what the heck!
We need to know just who are you?
If you are a criminal, or
If you might be mentally ill,
Say one or both, and say no more.
You flunk the check, cuz you could kill.
So legally - sorry, no gun.
Illegal gun you'll have to find.
So many ways such can be done.
That's up to you - hope you don't mind.

We'll know lots more of your background,
After you've been shooting around.
