Watch the Dallas police chief obliterate the myth of 'a good guy with a gun stopping a bad guy with a gun'

At a press conference on Monday, Dallas Police Chief David Brown shot down one of the NRA's most cherished myths that claims that the only thing that stops a bad guy with a gun is a good guy with a gun.

According to Media Matters, Brown was taking questions when he was asked about open carry at the event where five police officers lost their lives last Thursday night.

"We know that there was at least one gentleman who was a subject -- person of interest, during the demonstration he had an AR-15 around his -- around his shoulder," he was asked. "What does this tell you about people using the new Texas law of open carry at a demonstration like this?"

After finding out the reporter was a local, Brown went into detail about the position law enforcement officers have been put in by lawmakers who opened the doors to open carry advocates.

"All right, so, it's a little different here in Texas in the way we view open carry, concealed carry. We've had great dialogue with our state legislators about this. We've expressed all of our concerns. We are trying as best as we can as a law enforcement community to make it work so the citizens can express their Second Amendment rights," Brown explained.

"But it's increasingly challenging when people have AR-15s slung over and shootings occur in a crowd and they begin running, and we don't know -- or we don't know if they're the shooter or not, or they begin, it's been the presumption that a good guy with a gun is the best way to resolve some of these things," he continued. "Well, we don't know who the good guy is versus who the bad guy is if everybody starts shooting, and we've expressed that concern as well."

Brown added that he hopes Texas lawmakers will listen to the law enforcement community.

"I have every belief and trust that our folks are listening at the state on this issue, particularly as it involves protests."
