I understand that LTC classes could go horribly wrong.
I just find it ironic that, on the one hand, most members of this forum are against "red flag laws", yet, on the other, that's what this thread seems to advocate. Preventing an individual from receiving a LTC won't keep said individual from owning a firearm. It seems, to me, that the closest thing Texas has is Health and safet code - in particular Chapter 573 and it is vague as to how it works.
Returning their fee for the class and telling them, politely, to hit the road seems like a good idea.
Either we are all free or none of us are free.
