Cynthia McKinney's Attitude-Updated

She has a problem with it, according to James Taranto:

It seems clear that she has an attitude problem, and that this accounts for her history of run-ins with the Capitol Police...
McKinney's behavior toward the policeman last week might or might not have reached the level of a criminal assault; police and prosecutors will decide in due course whether to pursue charges. But her disrespectful attitude toward the Capitol Police is that of a petty tyrant, not a put-upon citizen. The officer who stopped McKinney was doing his job, which is to protect her and her colleagues. She owes him not only an apology but her gratitude.

As James also mentions, what if she had been a terrorist, and the Cop let her through?

Update: Her case goes to prosecuter.
