"The young lady in Kentucky is a professional activist ..."

I don't care who she is: a young woman with a sign is NOT a danger and does not deserve being thrown to the ground and stepped on.

"...a campaign worker intervened, not a trained policeman or security guard."...And what would you suggest a 'trained policeman' do to her?

Acts of harassment? Sure! Rand Paul has made himself a target for ridicule and harassment.
