Are certain weapons too destructive and powerful for the general public to own?

I have to laugh at the idea of any weapons ban. Is Beto going to go to Mexico and show us how to disarm the drug cartels? Hmmm? Will he send cops to collect guns, the same cops that let children bleed out while they stop parents from helping, because it is less dangerous to stop a helper than a single gunman?! How about the military, whose brass couldn't secure Afghanistan in twenty fucking years?!
