AUSTIN – The organizer of a mock mass shooting near the University of Texas Austin campus thinks media accounts of the event have been overblown.

The groups Come and Take It Texas and DontComply.com will stage what organizer Murdoch Pizgatti called "theatrical performances" Saturday to protest gun free zones. Pizgatti said the group will go through one scenario where the victims are unarmed and another where they are.

The plan caught national attention for its location and timing - coming less than two weeks after the mass shooting in San Bernardino - but also questions of its realism.

Pizgatti said the group would be using cardboard cutouts of guns and fake blood (ketchup, according to the DontComply.com website). While the groups plan to project gunshot sounds over a bullhorn, the sounds will be someone saying the word "bang," not the sound of actual gunshots.

"What people think is going to happen, and what it's really going to be like has a really big gap," Pizgatti said, "and they're going to see it's done well, and it's done with taste and it's not something that we're there to panic or leave a bad taste in anyone's mouth."

The group was originally going to play out the scenarios on the UT Austin campus, but university officials nixed that. Instead, Pizgatti said they'll move a few feet over to the public sidewalk.

The Facebook event for the demonstration had 88 attendees as of Friday afternoon.
