It may look like a dance-off but this swinging couple and dozens of others are moving for their First Amendment rights.The motley crowd took over the Jefferson Memorial in Washington DC Saturday to protest the arrest of five people caught dancing here a week earlier.A federal appeals court ruled that dance detracts from the seriousness of the monument.But the demonstrators say it's just another form of freedom of expression.Police closed the monument for an hour but made no additional arrests.
