Why "at least"? The couldn't before because public would be sensitive. Now with checkpoints everywhere, NSA spying, cavity searches, homeless people beaten down to death by cops getting away with it, DOJ declining to investigate bank scandals, IRS, Benghazi, Fast and Furious, they do not need logos with pink teddy bears and stills of a happy family holding hands with smiling children on the beach. The majority of public IS already got used to this tyranny. Coming forward with less PR is a next, obvious and logical step. After that: huge military boot on your face!
