Unintentional display or "printing" is not against the law. Intent is the key.

Had a gun and knife pulled on me in two stuations.

A guy pulled a knife on me when I was a restaurant manager, so I drew down on him (I had my P85 and the cops asked why I didn't shoot the guy at a range of 5 feet.). No charges filed against me, long story though. Later learned about the 21 foot rule in the academy. Kept my gun that night, as responding officers were regulars, knew I was not a dildo.

Had a gun pointed at me and two other deputies, we all drew and he dropped it. I was halfway through my trigger pull. As LEO, just had to fill out a buttload of paperwork.

Inadvertantly displayed as I walked into a local grocery store (shirt tail caught on pistol). Local officer pointed it out, checked CPL, "have a good day".

If you are not level headed, carrying isn't for you.
