Why advertise? Doesn't concealed mean concealed? I have heard of idots actually wearing them on thier belt like PD badges, while concealing the firearm. Not only does that open you up A) charges of impersonating a law enforcement officer,depending on local laws/ordinances, but much more importantly, B) being targeted by various criminal enterprises who love offing anyone with a badge. If such a thing was legitimate, they would be sold WITH the permit BY the state in question. As not one single state ISSUES such tin shields, I cannot fathom any such use for them whatesoever. Attempting to use one to ID yourself to PD during a "situation" may get you in deeper doo-doo than you were before!
If you want a real badge, see what you local, county, or state police have for hiring reserve officers, attend the academy, and do some volunteer work, as well as quality training in many avenues such as firearms, retention, driving, and arrest techniques.
I don't automatically call CCW badge users "wannabes", but that is what they will be tagged with. Bad idea all around. The other idea of drivers license/CCW permit being in the same folder is good - I set up my wife that way. One, it gives you a handy item to hand to police, and two, it lets you hand over your regular wallet to a robber without losing that ID....(and what were you doing in Condition White, anyway?!?!?) Also, more importatnly, it allows for a slim ID to be carried discreetly, just as your firearm, so women in tighter/fashionably pocketless clothing can still retain ID and permit.
That's my take on the whole subject.
