For reference of why my question:
Sec. 46.035. UNLAWFUL CARRYING OF HANDGUN BY LICENSE HOLDER. (a) A license holder commits an offense if the license holder carries a handgun...and intentionally displays the handgun in plain view of another person in a public place.

The way I look at it, every time I leave the house I'm probably breaking four or five laws I don't even know about.
