Do you have any stats to backup your feelings? I feel safe riding MARTA at all hours. (I live a block from Five Points and do not own a car.)

And Five Points used to actually just have gangs hanging out on the sidewalk before they cracked down two years ago. I've been threatened, but never attacked, on MARTA, but I'm a big guy (6' 5" and 210 pounds while I was taking MARTA), and nearly all of my female friends had a "a couple of people tried to block my exit and stop me from getting to my car" stories. My fiancee had two guys wait outside of the station exit gates saying "Here, kitty kitty" at night -- and that was at Sandy Springs MARTA. The east/west line is way worse.
