If you check the stats (ACE will look for a link to them later -- see continuation), you'll find the vast majority of those who get shot are shot between midnight and 4AM.
Another example was just after 3AM this morning in Atlanta , when there was a fatal shooting (several shots in the chest) just after Club 112 (at Peachtree & 12th St) closed down permanently. It was absolutely the latest one could get shot at Club 112 at its latest location. [11Alive report with link to video] Probably nobody will be charged.
A few years ago, some Atlanta clubs stayed open all night. Then, the city forced them to close at 3AM, as this copy of an AJC article notes. A 2005 "Creative Loafing" article described the ATL night club scene.
It's a free country, and I'm personally opposed to any restrictions on what adults can do, as long as they are not harming others, but I'm just saying you're chances of getting shot or stabbed before midnight are very low. If you're at home watching the Eleven O'Clock news, you're even safer.
The problem with GA carry law is it doesn't allow firearms in public places like bars, so unless you're violating the law, you're not going to be armed when you need to be most, which is from the bar to your car. They should allow customers to check their guns, like some places allow you to check your coats.
