Ah yes, the good old slippery slope fallacy. Again, this is really simple so pay attention. The drive to ban the assault weapon is not an attempt to stop crime or even the use of guns in crimes. It is merely an attempt to mitigate the damage from mass shootings, and perhaps cut down on their frequency. It is the simple response to a simple cost benefit analysis. Assault weapons provide little, if any benefit, to their ownership. Other guns can be used just as effectively, if not more effectively, than the assault rifle. Well, except for mass shootings, like children at elementary schools. The cost of their legality far exceeds any benefit they provide.
