Fed is easy to figure out just listen. he is saying he feels an ar-15 has a combination of attributes that makes it more deadly in someones hands then say a larger more powerfull weapon, that would have more recoil.
I also dont get why he is making that point though because he doesn't tie it in to how it should affect gun control.
Also still waiting for a liberal to prove 400 rifle deaths a yr is enough to warrant this much attention. Govt would be better off looking at things where more deaths occur if saving lives is the goal.
