Just a thought: can`t we just hard fork bitcoin to invalidate the coins in posession of the FBI?

It goes against just about everything I believe in, and yet I can't help but love that idea

yes indeed. I do not want to steal/invalidate someones money, but if we can just invalidate the coins in possesion of the FBI, it would be great

It would probably cause a hard fork with 2 existing bitcoins:
The ones accepting the FBI-coins, and the other ones

Maybe this is a great altcoin idea LOL
