All these idiots know up front that this is unconstitutional and will not stand up under litigation.
I think the real funny part is that such a conversion would render the gun far less dangerous.
There is a reason that the military and law enforcement don't convert their handguns to fully automatic. It's because it's a really stupid idea that only a pimp halfwit would do.
If the first shot misses the target the rest will to. The level of training required to effectively use such a weapon would be staggering.
