Gavin:
1.) You don't have to help or empower any law enforcement agency. This is not your job. This is their problem. It's not the problem of our community, if you want to act for us, then it shouldnt be yours.
2.) You are intelligent, you must known
a) they will 100000% extend the list of crimes you(btc foundation) needs to help fighting against (now its child rape, e.g. then its robbery, then its drugs deals, then they add political criminal act, until they arrive at their bullshit programm with copyright infrigements, trademark laws and so on)
and
b) they will 100000% abuse the controlling/freezing/anticrime/anti whatever technology you develope and implement for them (as they in history did with EVERY spy and monitoring technology, just read your US news papers or websites)
You know deep down in side your heart both a) and b) are true.
So I wonder, why you want to do this. You don't need this, stand up against this bullshit, Mike Hearn and all future other attempts by US agencies
Look at the TOR Project or Wikileaks, their project leaders and all core team devs tell any agencies to fuck off, go away, their will never be cooperation. Do it like them.
