A bad situation, but the stage was set long before this shooting....
Outside of Miami, Jacksonville is the most dangerous city in Florida.
Some parts (as in many cities) you just don't visit after dark!
After watching Jacksonville news for any period of time you can almost assume that if any type of confrontation, one side will have a gun (and use it).
A high number of black on black shootings in parts of Jacksonville. You can almost guess what part of Jacksonville the shooting took place before it's announced.
Large crowd incidents involving black youth are usually downplayed by the news.
A high drop out rate and many one parent families.
I could go on and on, but you get the picture, a picture that can be seen in many cities.
