OLMOS PARK, Texas – After huge crowds of armed gun rights demonstrators rallied in Olmos Park last weekend, several activists returned to meet with city leaders in person.

They are searching for answers on what they call unfair treatment by police.

Rick Briscoe, legislative director with Open Carry Texas, delivered hundreds of signatures calling for the resignation of Olmos Park Police Chief Rene Valenciano. The march was held after the group's founder, CJ Grisham, was arrested while openly carrying a rifle in March. A Youtube video, viewed more than 65,000 times, shows the encounter.

“The fact of the matter is that we believe the conduct of the chief of police is - simply put - criminal,” said Briscoe.

According to Briscoe, Valenciano did not follow the law and deliberately attacked several Open Carry Texas members, inflicting grievous bodily harm. Demonstrators said that there have been six other confrontations with the department since February.

“We make every effort to make sure that we’re not violating law when we come out. We’re 100 percent confident that we didn't break any law,” said Jack Miller, National Association for Individual Rights vice president.

After several confrontations with police, and recent arrests of gun activists, including Miller, Miller said the police chief is giving them the runaround.

“He doesn’t want to talk to us; doesn’t want to meet with us. His answer is I have no comment. I can’t (talk) about it, and he’s hung the phone up on me at least four times,” said Miller.

Miller’s case was later dropped after the ordinance was repealed by the city, but he still has other pending charges.

“But, I’m still currently under charges for criminal trespass and disorderly conduct carrying a rifle in a manner calculated to cause alarm – that stems from an open-carry out on the public sidewalk. I don’t know the details of what they are alleging because they refuse to release anything or say anything about it,” said Miller.

The advocates said the fight isn’t over.

“If the city thinks that we’re just simply going to go away and disappear, they’re mistaken,” said Briscoe.

The group intends to continue showing up in person until their questions are answered.

After several attempts to speak with Olmos Park city officials, Spectrum News was told they had no comment.
