Big Sister, Janet Napolitano, now has "public service" messages that are supposed to play in WalMarts encouraging people to report "suspicious" activities to the police. I guess there isn't enough paranoia out there so Janet has to stir it up. After all she has justify her assault on American scrotums somehow.
If you don't want to see Janet's mug at WalMart then let the company know. Unlike the Homeland Gestapo they actually have to keep customers happy, they can't use coercion against people, not like Janet and her thugs. WalMart can be called at (1-800-925-6278).
