Concealed carry classes continued as scheduled Saturday morning in McAllen, among the topics, the justifiable use of deadly force.
"Texas really is such a gun friendly state and the laws allow pretty much anybody, as long as they pass the background check and pass the course, to get the gun," CHL instructor Johnathan Ball said.
Groups like the Brady Center to Prevent Gun Violence are hoping to change that.
They have started an online petition to advocate for tighter gun laws, following Friday's shooting inside a movie theater in Colorado.
"I don’t think there's going to be any impact here," Ball added, saying it’s an uphill battle.
Instead, he said the high profile shooting in the Treyvon Martin case will likely have bigger implications.
"Where I see the debate going is more geared toward what happens in Florida, and whether we're going to have to start re-looking at issues of stand your ground laws," he concluded.
Nationally, the Pew Research Center reports support for second amendment rights was on the rise before the shooting.
According to polls from April, 49 percent of Americans surveyed said protection on gun rights was more important, whereas 45 percent inclined towards gun ownership controls.
