This list says Montgomery, AL is safer than Chattanooga, TN. Having lived in both cities in recent years, I'd have to strenuously object.
Chattanooga had a problem a few years back with so-called "home invasions". That activity ceased when a few of the 'perps were shot dead in the process....
Although I don't consider any city safe, Chattanooga is safer than most I've been through in my extensive travels....
And Tampa Fl. is by no means a safer city to live in then Saint Petersburg. I see a lot of improbable rankings in this list.
Also ranked Los Angeles, CA "safer" than Knoxville, TN. . . . . not likely.
