Even if these proposed executive actions would not be delayed by congressional lawsuits and obstructionism (as we saw with immigration actions), they overlook the fact that our background check system is so horribly flawed, the last 15 mass killers all passed their background checks. What is needed are REAL background checks, background checks that include interviews with people who know the purchaser (neighbors, family) and with the purchaser themselves. That is what is done in other countries and, notably, what the U.S. does with machine gun purchases. They work.
