Louder with Crowder had the man who stopped and chased down the mass murderer in Texas on for an interview. Some interesting things that came out of this interview - he was scared, he gave the Lord credit for getting him through this, he risked his life to do what he felt was the right thing to do, and he wishes the media would focus on the victims instead of him. He can't even go out of the house.
Other things he said: he had been an NRA youth instructor years ago, he was a dairy farmer, his rifle was locked in a safe unloaded, and he used an AR-15 to shoot the attacker with. He said the murder was wearing a Kevlar helmet and a ballistic vest. He also appeared to be looking for more victims.

This man exemplifies the definition of a citizen militia and why we have a 2nd Amendment.
