Stricter laws on smoking in and around public spaces are becoming the norm in states all around the country. In my home state of Virginia (a traditionally southern state), it's illegal to smoke in many bars now. Tobacco companies have seen tighter restrictions on their advertising (remember Joe Camel?) and are forced to print warning labels are their products. Additionally, tobacco products are taxed heavier than most traditional consumer goods.
Same with drinking and driving. Laws have gotten increasingly more severe for those caught driving drunk, especially for repeat offenders. Public awareness campaigns are a staple for almost every major holiday. How can you say people don't make a 'big fuss' about smoking or alcohol?
The difference is, we can (typically) have a sensible discussion on alcohol and tobacco laws, even with those that aren't in agreement. But when it comes to gun laws, the emotions are blown so high that there is a large block of people that won't even come to the table to talk.
Likewise, the argument is 'they will just find another way' is just as ridiculous. Sure, if you really, really, REALLY, want some one dead, you'll probably find a way. Even if the 'assault' weapons ban (including bans on extended magazines) was in place, it would still be impossible to prevent all mass shootings. But what if we can come to a compromise that might help limit the damages done by an deranged individual? Yes, a gun is a tool- just like a bike is a tool, a car is a tool, and a plane is a tool. Technically, I could ride my bike from the east coast to the west coast, but I can guarantee you that if my access to planes were limited, my trips across country would be vastly reduced. The access that we provides to tools does change behaviors.
