In White Settlement TX an attacker opened fire on churchgoers and was shot within 6 seconds by a concealed carry security volunteer. Listen to this interview of Jack Wilson, the man who shot and killed the attacker. He took his training seriously and was able to stop the conflict within seconds. It is apparent from the security video that this church was not to be trifled with, many other license to carry people were armed and responded to the threat within seconds.
Unfortunately two men lost their lives that day. Thankfully this church was prepared, otherwise this would have been much worse.
In September 2019 the Texas laws were loosened to be more permissive for licensed people to conceal carry in churches.
