You do have case law involving the cases in Texas charging CHL holders with allowing their weapon to be visible? Right?
As I mentioned much earlier in this discussion thread, I'm not able to locate any case law regarding the matter. For those who are so confident that "printing" is not illegal, then I welcome them to see just how much they can "print" before it becomes an offense.
My point is that this is still very much a gray area and has remained untested by the courts. The blanket statement that "printing is not illegal" is overly broad and can get one in legal trouble, because there are many degrees of "printing". I would prefer to err on the side of caution and would suggest that others do the same. It's likely that most CHL holders are in fact erring on the side of caution, because we have not come across any test cases yet.
