MS: Football prayers — district caves, fans pray anyway District Attorney Keith Treadway believes the law prohibits prayers over the public address (PA) system at sporting events, but Kelly Shackelford of the Liberty Institute says the Freedom From Religion Foundation is misinforming people. “You have a right to speak a religious thought, even if it’s on government property, even if it’s on a PA system that’s government -owned, even if it’s on a public street, a public park, which are also government property,” he contends.
