Check out the Midtown Blue website - they are the private security force that augments APD's Zone - the site is in the web reference.
Check out the Zone 5 web page and stop in their precinct office for more specific reports - ask for the beat books for the specific beats that interest you. Here's their page - http://www.atlantapd.org/index.asp?nav=Zone5
Otherwise, if you live inside the city limits of Atlanta, then you are 4 times more likely to be the victim of a crime than if you live outside the city limits. I read that somewhere a few years back and quote it frequently because I find it refreshing...
Crime "rate" is very relative, so you gotta go get your own data - you won't find it here on Trulia.
One more site for insight - Policy Maps' website for City Crime Rates and Statistics - it's for data freaks only - http://www.policymap.com/city-crime-rates/index.html?gclid=C
do a google search for the following words: 30363 police stations. then take some time to call them all and ask them about crime. there is crime there... it's Atlanta. good luck.
