15 | Mass shootings and gun sales, CNN article, October 3, 2017

There's no better way to sell guns than with a false flag involving a mass shooting.

Notice the mention of 15 million gun sales per year.  That's a bullshit stat.  I guarantee it is way higher.  There's a lot of gun nuts in this country.  Gun = 7+3+5 = 15

I think one of my uncles buys almost that many alone per year, plus crossbows.
