Violent crime rate is just another statistical ploy to deny the success of the ban on assault weapons.  Violent crime rate includes all other violent incidents besides just guns.  The key factor is the absence of mass casualty incidents from assault weapon use.  The only statistic that is relevant.  All other lumping together of statistics is just red herrings of circular logic with a pre-programmed result only using statistics that support the assertion.  Try reading something besides gun magazines for education.  The only use for assault weapons is to slaughter human beings in huge quantities.  They have no other reason for existence.
