Don't mess with Texas.

A viral video shows a shotgun-wielding man guarding a Houston grocery store from alleged looters amid the Hurricane Harvey flooding.

In the video, which was posted to YouTube on August 29 by user TexasProud, the self-proclaimed "ex-SWAT deputy" warns people who appear to be ransacking the Little York Food Mart.

“Hey, don’t go back in that store! I’m telling you one time. I’m not scared to shoot you," he says. “I’m an ex-f***ing SWAT deputy! I will cut your a** in half."

The alleged looters appear to run away after the warning.

“It’s a shame. We need more real men out here to step up and protect where you live,” the armed man tells the woman behind the camera. "This storm is temporary."

“[I’m] protecting the community where I live. I grew up in this area. I’m a former law enforcement officer, so I understand what the law says," he says. "If you’re looting, you’re stealing. It’s a violation of Texas law and federal law in the time of a catastrophe."

The woman filming the video praises the man for his efforts, and she tells the camera that the media isn't reporting on the robbing and looting that's occurring in Houston.
