Security has been beefed up on “Dancing with the Stars,” due to the wacko who’s been sending threatening messages to ESPN’s Erin Andrews. A man in Newport News, VA, has been sending the violent e-mails via DirecTV’s “The Dan Patrick Show.” On March 29, the man sent this message: “I would like to see if Erin Andrews can dance her way through a hail of gunfire. Better yet I would love to shoot her with a Barrett rifle. Get the pun — her stalker was mr. Barrett and the barrett rifle is an ultra expensive 50 cl. rifle with a range over a mile.” The producers of “Dancing” are taking this very seriously, and are searching every car entering the CBS lot on taping days We’re hoping the FBI nabs this guys soon! Stay safe, Erin.
