wants to get a gun but cannot legally. Check out the want ads in the sporting goods section for firearms for sale. You call the guy up and ask about purchasing it and looking at it before the sale. You find out that the gun is in the sellers home and that you can come look at it anytime after 6 pm as no one will be there to show it to you till then. Then the seller will meet you the next day at the gun shop to do the transfer. The bad guy now has a time and place to break into that he knows has a gun in it.

Now I understand that that CAN (and probably does) happen now but if NICS is required on private sales this kind of thing will likely happen very often.
