In 1926 you could mail-order a Thompson SMG or a Colt Monitor with the only delay being the post office for your check and shipping time to your door. Full auto, no background check, no registration.
In 1926 Al Capone was in charge of much of the crime in Chicago.
26 murders in 1926. That's 16.7 per 100k.
In 2012 you cannot mail order any kind of firearm and owning a machinegun requires both registration and a background check. None of that matters because you can't own one in Chicago and most regular firearms are very tightly regulated.
Al Capone is long dead.
532 murders in 2012. That's 19.7 per 100k.
Yup, gun control is working alright.
By way of comparison.
In 1926 Jacksonville the murder rate was 76.9 per 100,000 people!
In 2012 Jacksonville, FL had 108 murders, a rate of 13.1 per 100k.
In 1926 Tampa, FL had a murder rate of 67.6 per 100,000 people and last year it was 8.1!
Since the mid eighties Florida has made it much easier to buy and carry a firearm and to use one at need.
When you start talking about making the streets safer, make sure you check to see what actually works.
These statistics were far too easy to find online, so the gun control people are either willfully ignorant or lying about the purposes of their laws.
After watching them closely for the past 20 years, I think they are not ignorant.
