Texas is a "cross" between KALIFORNIA and ALASKA.
That is in large part because Texas is a runner-up in the competition for the "biggest sate", and now is competing for the most "populous state" honor - WHICH IT WILL SOON ACHIEVE.
I would estimate that 3/4 of Texans would (if they had legislative initiative options)vote for "constitutional carry" like Arizona. In other words -" If you ain't bothering nobody with your gun - then carry it."
LEO's (Texas and otherwise) THANK GOD - DO NOT MAKE OUR LAWS. They are responsible FOR KNOWING THE LAW, and enforcing it-period. The LEO's opinion cited by the OP is correct in regards to failure to conceal by a concealed handgun licensee in a "BAR" failing to conceal a handgun INTENTIONALLY, KNOWINGLY, or RECKLESSLY. Other wise INTENTIONAL failure to conceal a handgun by a licensee is a Class A misdemeanor in Texas- if it can be established that the failure to conceal was INTENTIONAL. Not coincidentally that is the same penalty for DISORDERLY CONDUCT.
Texas law does not criminalize concealment of a handgun per se, or require concealment except for licensees, and unlicensed vehicular carry. A " traveler " in Texas is provided by law with an open carry OR concealed carry affirmative defense to the section 46.02 handgun carry offense when in direct route TO HIS/HER VEHICLE - which implies PROXIMTY TO THE VEHICLE.
I believe that the OP from UTAH would be a positive contribution to the effort to restore handgun rights in Texas. The economy in Texas is in great shape compared to the rest of the lower 48 states, and freedom loving people are always appreciated and welcomed in Texas.
Just let me say this - The whole issue about "failure to conceal " in Texas centers on concerns that individuals may be prone to intimidate, menace, threaten, bully (what ever you want to call it ) by DISPLAYING A HANDGUN - EVEN HOLSTERED.
Most folks in Texas are not going to get alarmed by the sight of a holstered handgun DEPENDING upon their PERCEPTION of the individual in question. Therein lies the problem. This is true even in the open carry states.
This is why it is paramount that those who undertake "open carry" do so in a LEGAL, and PRUDENT manner. There will ALWAYS be a backlash to "EXTREMISM".
OPEN CARRY in ANY state should only be engaged in after soberly considering the environment, and the circumstances. Human perception makes a distinction between 2 or 3 yound males ( Blacks wearing dew-rags, Hispanics with body tatoos, or White "skin-heads" ) "hanging out"(loitering) in the public square with handguns in, under, or attached to their belt ..... and say.... a middle aged fellow walking his wife along the "river-walk" (in either Pueblo CO, or San Antonio TX ) in a wheel-chair while wearing a Glock 23 in an IWB holstered that is hardly visible.... in the same environment.
THREAT - or NO THREAT ??? You tell me.
Should the OP relocate to Texas - or stay in Utah ? Personally - I think Texas will eventually be revealed as the most 2A friendly state in the Union - BECAUSE of the State's historical heritage - and the native culture of polite respect for the rights of others.
