We've been around this block before when it comes to the definition of "concealed." The operative word is "openly." I still do not want to be the test case to decide that legal definition. Note that the definition relies on "ordinary observation of a reasonable person." We have discussed juries and reasonable persons in many instances here in Texas, and I'd say that a "reasonable person" that detected a gun on your person where the outline is clearly visible (under a T-shirt?) could interpret that as "openly." You be the test case, have the arrest record, take the ride, pay the attorney(s) and "hopefully" I'll be wrong. It's just not going to be me
Sec. 411.171. DEFINITIONS. In this subchapter:
(3) "Concealed handgun" means a handgun, the presence of which is not openly discernible to the ordinary observation of a reasonable person.
Note: I base my opinion on "my" interpretation of that sentence as the "presence" of the handgun is openly "discernible" (the "presence" is clearly visible through the cover garment), not the handgun itself so to speak. MHO
