The newspaper publishing locations is hardly the government coming after your guns. So yes, it is far fetched to think the government was going to do something. This is purely a matter of capitalism (newdpaper wants to sell copies) and freedom of information.
Waiting periods TOTALLY make sense - not sure how you could not see this. John walks in on his wife cheating on him. John walks to pawn shop and buys gun. John shoots cheating wife and dude. With a waiting period, John would have to wait 3-10 days for said gun. He would then have time to think about shooting his wife, and would probably not do it. As you can see, waiting periods can very easily lower the number of "crimes of passion."
And NYC doesn't "stop and frisk" anymore. Has the crime rate gone up?
Depending on the source, you can argue stop and frisk made crime go down.
If some guy is going to kill his wife in an act of passion, he's doesn't need a gun to do it. I've never seen evidence that crimes of passion go down because of waiting periods.
The newspaper had demand for issues being sold because ppl wanted to know who had guns, and many of those ppl don't want their neighbors to have a gun at all.
Many cities would outright outlaw guns IF THEY COULD. The 2nd Amendment has stopped that. Again, look at Chicago, DC, and even the laws of NJ. Will the federal govt come get them? Maybe not. Will local/state governments come after them? Yes, absolutely.
