3. the point is ... if a guy is determined enough to cause carnage ... then having a single barrier is
like having no barrier at all ..
so apart from banning high capacity magazines - you need to impose multiple barriers - ban on semi automatic guns, have waiting period before any guns can be purchased , universal background check incl private sales, registry of firearms, annual renewals, tax home storage of guns, limit on ammo puchases each month .. make them file ammo usage reports each month ( by mail)
Basically make life miserable for gun owners ... that will reduce demand and in turn reduce supply .. ie ..cause the industry to shrink the point that a lot of dealers will exit on their own ..
with reduced availbility ...a mass shooter will be forced to be really resourceful to act upon his evil plans.
