However, to answer to the "cars" analogy...this area (traffic) must be covered with various laws - you must have driver exam, a licence, fasten the safety belt, respect the speed limits, no alcohol, and various other regulations. Of course, IMO - similar laws/limitations must exist about possessing, carying, using, etc. of various firearms.
But, I noticed that this is a hot right/left political question in USA, and I can`t be a part of this. I only can say my opinion that I hate to see the statistic where`s more then 30.000 dead from guns ab(use) every year. I live in the town big like that...
