Video Shows Aftermath of Texas Mass Shooting, Chaos Inside Austin Bar

Here’s what it looked like after a gunman opened fire inside a Texas bar over the weekend, killing three and injuring more than a dozen people … some folks are hiding and some don’t seem fazed.

TMZ obtained video from the aftermath of Saturday night’s mass shooting at Buford’s Backyard Beer Garden on Austin’s West 6th Street … and you see bar patrons cowering in fear, and hiding behind tables and columns.

At least a couple dudes were more interested in taking photos of themselves amid all the death and destruction than actually looking out for their safety … you can see them boldly taking each other’s photos in the middle of the room.

But, the vast majority of folks look like they’re scared out of their minds … and for good reason. A gunman had just shot up the place.
