On Saturday, Texas gun rights activists are holding a rally at the Alamo, a location that’s been rally-free for at least the past 100 years.

The rally, called the “Come and Take It San Antonio!” rally, is in response to the non-custodial arrest of three open-carry advocates in early August, who were charged with disorderly conduct for openly displaying rifles at a local Starbucks.

While it’s illegal for one to openly carry a handgun in the Lone Star State, openly carrying a rifle is not against the law as long as it is done in a manner that is not alarming and non-threatening.

However, in this case, San Antonio Police Chief William McManus argued that because a woman felt threatened, the dis-con charges would stick.

“It’s a disorderly offense that officers will address accordingly,” McManus said.

Today, gun owners will gather at the Alamo in protest of both arrest of the three men and a San Antonio ordinance that restricts firearms in public parks or at political rallies.
