Gunman Unhappy With Programming At Discovery Channel

A gunman who held three people hostage, at the offices of The Discovery Channel, and who was later shot dead by police, had a dispute with the channel over programming. Of all the bad programming out there the guy had a problem with The Discovery Channel ? Who's next ? MTV, FOX,BRAVO, if that was me I'd start beefing up security now. How long before a crazed husband comes looking for the creators of all those Housewives shows?
