Where have I blamed anybody EXCEPT for the vegas killer? 
And where have I said that we do not require background checks. 
SHOW US without your posting things in my name otherwise, you are just another liar.
Good luck with that. 
 
Secondly, the laws/regulations are a JOKE. 
The idea of stopping ownership of large magazines is a joke, esp. when those are actually easily printed (and with new designs that operate better). 
However, at the same time, the idea of putting ZERO regulations and holding NO GUN OWN responsible for their actions (such as making sure that firearms/ammunition remains out of kids hands) is just as twisted. 
We should have 3 levels of licensing which then enables you to buy firearms and everything associated with it.
If you will, which requires simple background and hunter's safety class, enables you to own and use anything below any automatics. 
Second level has more background check and training after say 2 years of above, and gives you semi-autos. 
Etc.
