Gun control, or fear control?

Just because an argument is very persuasive, doesn't mean that the point being made is correct. Kinda like how a good salesman can make almost anything seem worth almost any price. So when people talk about gun control, are they right, or are they making persuasive arguments that are not backed up by the data? It is worth it to make sure you are looking at the big picture, and not just one piece of select data.

People make the point that gun-related deaths goes down when gun-control policies are put in place. Of course they do! But does the overall death rate go down, or do people just switch to different methods (looking at both suicides and murders)?

Here's an interesting study on the history of gun control in the UK. It provides but one small picture into this huge debate.
