Obama doesn't give a rat's a$$ about banning guns to save lives. In fact, it's exactly the opposite, the killings in Newtown was an orchestrated plan to force a gun ban that will ultimately disarm the citizens of the country. Then, he can unleash his DHS army, have drone strikes and kill as many of us as possible to enable him to keep control of the presidency.
If you don't think it can or will happen here, just look up some fun facts in the history books. Neither did millions of others, till their own government slaughtered them.
The gun ban is a bunch of smoke and mirrors.
