Atkinson’s letter comes after Texas Governor Greg Abbott signed a bill that made it legal to carry a firearm openly in Texas. The law, which gives private property owners the right to prohibit open carry, was hailed as a victory for gun rights advocates who have staged high-profile rallies at the Alamo and Texas Capitol over the past couple of years. Some even brought military-style assault rifles into businesses as part of their demonstrations, prompting the Chipotle restaurant chain to discourage firearms on their premises.
