Higgs epitomizes the ignorance of the anti-2nd amendment, anti-Constitution, anti-Self Defense, and anti-gun crowd. It's bad enough they spew their ignorance, it's worse because it's WILLFUL. They make NO attempt to fact find, and I doubt any of them have ever had an original thought on the subject.  
Again, if Higgs bothers to read responses, an "Assault Weapon" IS a military weapon.  It is selectively able to fire full, semi and burst fire. They are NOT sold in the civilian marketplace.  (AR is only the designation of the original company designing & selling the item:  ARmalite, the "15" is their 15th rifle).  The erroneously named "Assault Weapons Ban" was a "sunset" bill, and when it was shown to have no effect on shootings, it was not renewed (not to mention that any federal Gun law is unconstitutional!) For your willful ignorance, write on the blackboard "A Semi-automatic Rifle, no matter how scary looking, is NOT an Assault Weapon."  Do it 1000 times or until it sinks in!
