No clear answer, but evidence does exist.
I'm certainly no expert on the impact of violent movies, music and video games on the propensity of a person to commit acts of violence. Like many folks, for years I scoffed at the idea that there was a cause and effect relationship between violent movies and violent acts. I still believe that there is no link between violent movies and violent acts except in rare occasions when a person is already prone to violence and the movies feed their fantasies. I base this on articles written by mental health professionals.
Texas Gun Sense lied about Umpqua Community College’s “No guns” policy
What do Texas Gun Sense, Moms Demand Action, Mayors Against Illegal Guns and other Bloomberg-funded anti-gun, anti-Second Amendment groups have in common? Lying and deception are their modus operandi. In some ways it is understandable since the facts do not support their agenda, but one would have hoped that honesty and integrity would have been of greater value than a political goal.
A few days ago, a small group of protesters gathered outside of the Houston Zoo to complain about the City of Houston’s order that unenforceable “no guns” signs be removed. These signs purported to be posted in compliance with Tex. Penal Code Section 30.06, but there’s a catch. Section 30.06(e) clearly states that such signs are unenforceable when posted on property owned or leased by a governmental entity or agency. (Section 30.06(e) was enacted in 2003.) Therefore, it has been perfectly legal for Concealed Handgun Licensees (CHLs) to carry their self-defense handguns in the Houston Zoo for over twelve years.
