Very strange indeed, I think there are alterior motives, check out their wording, "I believe to be successful the key to concealed carry is training," said St. Clair County Sheriff Mearl Justus, voicing his support Wednesday. "If we allow concealed carry, we must make sure only the right people have the guns. This is best done by requiring training, proper identification, and a thorough background check — including a mental evaluation."
I think it is a backdoor into restricting or banning concealed carry, if you are taking antidepressants or any number of other medications they will use it to judge you unfit.
This makes no sense for the Illinois sheriffs association to back concealed carry now, they have opposed it forever.
