AUSTIN (KXAN) — Demonstrators gathered across the country Saturday to show their support for the second amendment including at Austin City Hall. Organizers called the event "June 2nd for the Second Amendment" and invited those who have the proper documentation to bear arms in a peaceful demonstration. Police were on scene to monitor the event and ensure violence did not break out. Supporters of the second amendment highlighted that it is Congress’ job to uphold the Constitution and all of its amendments. "This is not a granted right by the Constitution nor is it any manner dependent upon the instrument for its existence,” said one person attending the rally. “The Second Amendment declares that it is a pre-existing right that shall not be infringed." In 2015, Texas lawmakers also passed a bill to allow open carry. The law lets people who have a permit carry a handgun openly. Previously, state law forced permit holders to conceal their guns.
