tweake: even the guntubers where complaining about that. so many untrained people where buying guns for self defense but not getting any training. thats how the problems start. 

Someone on YT, possibly John Oliver, ran a video where they put Joe Sixpack with a gun through a police training exercise involving an active (simulated) shooter.  He ended up getting killed several times, and shot a lot of civilians, but never got the shooter.  My neighbour, ex-military, said they fired (from memory) something like 3,000 rounds a year in constant training.  Members of Meal Team Six OTOH, who shoot beer bottles off a fence a few times a month without any of the beer bottles shooting back, would last about 30 seconds against someone with actual training and experience.
