Ask Slashdot: What's the Best Way To Deal With Roving TSA Teams?

An anonymous reader writes "I live in Boston, and I have noticed the TSA performs random security checks at the Copley T (subway station) and other locations. I routinely travel with a laptop, iPhone, and other gadgetry. What are my rights when asked by one of the TSA agents to 'come over here'? Can I say no and proceed with my private business? What if a police officer says that I 'must go over there and cooperate'? Can I decline or ask for a warrant? Like the majority of the population, I turn into an absolute shrinking violet when pressured by intimidating authority, but I struggle with what I see to be blatant social devolution. Has anybody out there actually responded rationally, without complying? What were your experiences?"
