Make one disappear and see who comes looking. Then you will know who they are.
Matching uniforms. New flags in perfect condition. Very few organizations have the funds to purchase all this stuff, certainly not an organization as unpopular as 'Nazis'.
There is, however, a nearly-unlimited source of funds at the FBI.
FOLLOW THEM and SEE IF THEY HAVE A GHOST BUS TO PICK THEM UP!!
Good point.
