Full text of bill at HB 991 - House Committee Report version - Bill Analysis.  Under current law, anyone can discover if anyone else has a CHL by submitting that person's name and paying the required fee.  They get a simple yes/no answer.  Full lists of all CHL holders in Texas are not available to anyone, including allegedly "authorized journalists," so publishing a list of all CHL holders isn't legally possible, although I suppose some real scumbag could leak it if they really wanted to.

H.B. 991 removes the requirement that DPS (Department of Public Safety) disclose to any person, other than state and local law enforcement agencies, whether an individual holds a concealed handgun license.

I'm trying to think of what the Brady Goon Squad is going to call this in their next lie campaign, but I can't come up with anything.  I guess I just don't have that mind-set.
