TR, with all due respect, it doesn't happen often, yet it does happen. One of my former students had a "stupidity spasm" outside of Marfa about a year ago.
It appears he had a temper anyway and he was drinking ( already legal in Texas ).
He started a verbal argument ( a no-no when carrying ) with a Hell's Angels wannabe.
He escalated the verbal argument ( a no-no when carrying ) and took it outside to the parking lot.
He got into the guy's face and sliipped out his Keltec 32, slipped it upder the guy's chin and set it off, killing the biker ( another no-no). Killed someone on verbal provacation alone.
Although it doesn't happen often and there is no bloodbath, some folks that get a CHL that are already marginal in the impulse control department get extra stupid after drinking, even a little.
They figure they'll display the gun just to shut someone up and then an accident happens.
The legal counsel at DPS ( the actual person that appears in court to take away your license ) said that over half of the total CHL revocations are alcohol related in some fashion. Those statistics are imbedded in other crimes lsited on the DPS website.
Still legal to drink and carry in Texas, yet I'm just sayin'...
If you need more details, I can dig around at the academy this weekend for info or ask the constable about it since he went to the hearing for this guy.
