Americans should tax gun and bullet sales with an assessed tax based on the criminal harm carried out by such weapons.  Tally the cost of the dead, the dying, the wounded, the hospitals, the court settlements.  Justice system and business costs.  Everything into the bucket.  Then tax the heck out national arms sales, guns and ammunition.  Break it down by categories, like vehicle insurance.  A shotgun would likely cost less than an automatic.  Figure it out.  Then if you want to own one?  Fine.  But you'll pay for the actual cost of these weapons. Let's be business like about it.  Trump seems to want a cost on everything.  Let's put one on the actual harm done by guns involved in all criminal activities.  You want to strut with a gun at your side?  Pay the real price involved.
