It depends on what you define as failure. If success implies a drastic shift in power from law-abiding citizens to thugs and authoritarian utopianists, they're doing quite well.
This (has been) only in DC and a few other out-of-touch backwater leftist enclaves (like San Francisco). In case anyone missed it, the 2004 election has reinforced te concept of law and order as a paramount ideological requirement.
BTW, I am more than pleased to abet this effort, upon request (or not). Despite the death rattle of the Left, We The People are ever avail our natural right of self defense against our oppressors. The current war against radical muslims ought to leave this more clear than ever.
