Sheen must not be terribly bright, most people with his fame and resources hire professionals to threaten people. I’m not saying it’s right, but thats the way it usually happens.
With all good luck, this will cause that horrible tv show "2 1/2 men" to be removed from the airwaves forever. Just a terrible show, and not worthy of airtime especially around the dinner hour with impressionable kids near the tv. Poorly written and low-class.
