Gotta love the bias in that article:
Some supporters of the bills say responsible gun owners are not the ones attacking school children. Texas Department of Public Safety data shows that of concealed handgun license holders, who had to pass background checks, were responsible for 120 convictions in 2011, many of them felonies.
The author of this article is apparently trying to link "attacking school children" with "120 convictions, many of them felonies." They also intentionally fail to mention how many felonies are committed by non-CHL holders, and how the ratios compare. It was good to hear Alice Tripp bring up the fact that CHL holders are 15x less likely to commit a crime.
