If you look in my cite of the law, you'll not that the exemption is only for LEO's "acting in their official capacity". While one may make the case that off duty LEO's in Texas still have their jurisdiction...hence are always "acting in their official capacity", this seems to be tougher if you are out of state or carrying under the retired provisions of LEOSA. Perhaps another reason for a Peace Officer, or at least retired LEO to get a CHL.
