Pittsburgh Tactical Firearm was giving away an AR-15 assault rifle on its Facebook page. Facebook shut down the account and the owner, Erik Lowry of the shop tried to start another page but that too was shut down by the site. The owner says he doesn’t understand why Facebook would shut down his page and said he tried contacted them but hasn’t gotten any response. Facebook has a policy that prohibits ads that promote weapons and firearms, which clearly this giveaway contest is doing but the owner disagrees. “There are no guidelines that say you can’t give away guns,” he said “This kind of censorship is unconstitutional.”
