Bingo. Not sure how this can be Disney's fault, or how an increase in Disney Security in the employee parking lots could have stopped these muggings.
Metro Orlando has one of the highest per capita crime rates in the nation, and made the 25 Most Dangerous Cities in America list again, etc., etc. It's been that way for years and years. The adjoining city of Kissimmee also has a very high per capita crime rate. These are not safe cities to wander around in, and the CM's who were mugged on their walk back to the apartments at 1:00 AM need to be aware of that.
If there's any responsibility Disney has in this, about the only thing I can think of is it would be nice if Disney could provide training and communication to their CM's on behaviors to use to avoid being the victim of a crime. Walking along a road at 1:00 AM in a statistically very high crime area with an expensive cell phone in your pocket is not a good behavior, unfortunately. Thankfully no one was injured or killed!
