President Obama and his fellow travelers use the numbers...

...that will push their agenda, even when they know those numbers are utter bullshit. Remember the Mexican canard?

Gun Sales and Background Checks: Obama’s Bogus 40 Percent Stat

The all knowing and powerful Obama says 40% of gun sales take place without background checks. Let's add the word legal to that just to clarify. Criminals don't bother with background checks. This 40% stat is based on a two decade old study made before Brady changes the rules on when background checks had to be made and it was suspect then. In the year 2013 it supports nothing. Bloomberg and Obama don't care. It furthers an agenda. All it does is prove the old adage, lies, damn lies, and statistics. Oh and a prohibitionist will do whatever it takes to win...even lie.
