Jacobs said he hopes some searches will result in the discovery of guns they didn't know were in their own homes.

I'm assuming I'm missing something here. 

How do police intend to search houses for guns the residents didn't know were there? If it is in the house proper, surely the residents brought it in. If it was in the house prior to move in, it would have to be under the floor, or in the walls. The only time I have ever heard of this happening, the firearm had been drywalled into the ceiling. How do police intend to find those? If they do find them inside a wall, what do they intend to do when they do about it?

I will confess to not knowing what tragedies can occur when toy guns have been altered, or what relevance toy guns have to a police search for real guns. I'm going to call, "they Emporer has no clothes" (there are no tragedies that occur because of altering toy-guns).
