On Friday, Perry called on all Texas school districts to review their emergency operation plans.

When discussing the shooting Monday, Perry's voice "broke and he paused several times." He dubbed the shooting a tragedy that “is not right" and referred to Adam Lanza as a "young man who was very disturbed."

But he hoped that Washington's reaction would be a well-considered one: “One of the things that I hope we don’t see from our federal government is this knee-jerk reaction from Washington, D.C., when there is an event that occurs, that they come in and they think they know the answer,” Perry said.

Twitter erupted with skepticism over the idea: 

But at least one Texan gun store owner supports Perry's message. Crocket Keller, owner of Kellers Riverside Gun Store in Mason, extended a discount to teachers who wanted to arm themselves. “We need to start thinking out of the box and deal with this violent culture,” Keller told CBS DFW. “We need to lobby our various state governments to allow teachers to be armed.”

Keller generated headlines last year when he ran a radio ad in which he said he wouldn't offer his Concealed Handgun Classes to "non-Christian Arabs or Muslims" or people who voted for President Obama.
