You're not making any sense here.
Your right to own firearms does not trump any other right, less so the rights other have to be alive.
The fact that gangs will get weapons elsewhere is a lame poit as well. As is, they choose to get their weapons from us because it is the easiest and cheapest way. The point here should be to make it as difficualt as possible to obtain these kinds of weapons. Americans would not be giving up freedom by putting the ban in effect. That's such a vacant statement.
If the inability to own an assault rifle is tantamount to a loss of freedom, then how did freedom exist prior to the assault rifle? If this is the case, then we aren't free until the invention of the laser rifle! This is silly. You do not need the ability to buy an assault rifle to be free.
Your disregaurd for the lives of the Mexicans caught in these violent bloodbaths is chilling.
