Umm...did he imprison them? I thought the article said he turned them over to authorities.
Holding someone at gunpoint is considered imprisonment under the statute. And unless he witnessed them breaking into his house, they were probably engaging in misdemeanor simple trespass.
He did, but the authorities don’t live on his ranch. He held them until they arrived. (If I read the article correctly.) There’s also something about kicking a woman, which I highly doubt.
