The "war like" was hyperbole. In the just under 5 years that the FReepers in the DC area have been demonstrating, NO FReepers have been arrested and NO FReepers have initiated any violence.
And the police (God bless the U.S. Park Police, U.S. Secret Service, DC Police, Fairfax County Police, among others) have kept us relatively safe from those who wish us harm.
Have a great FReep!
