You make it sound like the off-duty deputy was possibly there just to enjoy a movie, perhaps..... and made the split second decision to engage the shooter. She was there working SECURITY. She did her job as she has been trained by the sheriff's dept, & I'm glad she did. This was not some common citizen with a concealed carry permit.

"Detective Louis Antu, spokesman for the Bexar County Sherriff's Office, said the shooting began at a nearby China Garden and “carried on into the theater.”

At one point, the suspect fired at a San Antonio Police Department patrol car, Antu said.

“He was shooting at a marked unit,” Antu said. “He knows he was shooting at an officer so that's (an) automatic (charge of) attempted capital murder.”

After the suspect reached the theater, an off duty Bexar County Sheriff officer who was working at the theater shot at him and possibly struck him, Antu said.

“She took all appropriate action to keep everyone safe in the movie theater,” Antu said."
