Charlie Sheen had better watch what he says about his ex-wives during his Torpedo of Truth tour.
Their goal is to monitor what Sheen says about them, in case it's needed in legal proceedings.
At Sheen's Chicago appearance, he made comments about Mueller, who recently gained temporary custody of their two children after a police raid at Sheen's house.
On stage, Sheen said, "The kidnapper. Nice try. She sent 9,000 cops to my house to look for some guns."
"Tell me, what did they find?" asked Sheen's friend on stage.
"They found one gun, from 1848," said Sheen.
