There is another form of tyranny at work here that seems to have been missed in this thread; tyranny over legal behavior and attitude.  Assault weapons bans don't really address gun crime; they seek to criminalize attitude and behavior; people who like assault rifles, for whatever reason.  Perhaps assault weapons ignite commando fantasies in some, or perhaps the owners just think they're cool.  None of these attitudes and behaviors are the government's business.     
  
It seems that a bankrupt nation paying for 2.2 million people to sit in prison; the highest incarceration rate in the world, migth consider that idea of making fewer things illegal, rather than more.  
  
Having said that, there are posters (not you, Bill) here who celebrate the loss of habeus corpus and the use of torture, yet rail against any form of gun control because it leaves citizens helpless in the face of tyranny.  To those posers: you're willing to fight an imaginary tyranny that will probably never happen, but support tyranny that's happening right now.  Guess what?  That's exactly what happened in Nazi Germany, the gun proponents favorite pet historical example.   
  
In short, you're not part of the solution, you're the problem.
