Chris Hayes had a great monologue last week, or maybe after the Buffalo shooting, explaining that statistics show that mass shootings are great for the gun industry, because after every mass shooting gun sales go up for a variety of reasons including public fear and after mass shootings there is always talk about gun control. So the NRA and the gun industry LOVE them some school shootings, because they're great for business. That explains why so little was done at their convention to recognize or mourn the of murders caused by their products.
