How about shaming this govt rabble with a mass march, all in suits and RAF ties - about the closest thing you would get to a Regimental uniform. Walk down Whitehall to No 10 and form up before having an about turn to face away from Downing St and the MOD.
It would be a powerful statement of how exactly we felt about the Govt and if done peacefully would shame the Govt - especially if they sent the heavy mob in to break it up.
I seem to remember a group of veterans turning their backs on a dignitary in a parade not so long ago which got an awful lot of publicity for their dignified way of embarrassing said dignitary.
