rifles into a machine gun. we did have video of what one of those manufacturers it's called a slide stock or bump stock what that does to an actual semi-automatic leely purchase weapon. and the video just shows the stream of bullets coming out very similar to what we were hearing from all that happened at mandalay bay. so that's where the investigation on the motive is becoming so so tedious and so far without any answers. but also, as this moves to this whether or not we do anything at this time to look to see to ban or limit any kind of guns, why it's so troubling i think for the pro second amendment folks who are basically saying only criminals should get guns and we have laws to enforce to keep those cs from getting those guns anderson? >> drew griffin, appreciate that from orlando.
