>>People in gated communities tend to relax their precautions in keeping doors locked and more than likely had expensive things to steal. Zimmerman, high on pot, must have felt like he was a kid in a candy store.<<
(I think you mean Trayvon, not Zimmerman)
Actually, this particular gated community was on edge because of numerous recent burglaries, including one when the wife and child were at home.
By any objective measure, it was not an affluent area. The condos had lost more than half of their value, with several being bank owned. You can see them if you google 1111 Retreat View Circle (the clubhouse address), Sanford, FL. Looking at zillow, the sizes are 1,200-1,500 square feet with only one car garages, not what most people would describe as affluent, but still worthy of breaking and entering to someone who needed money for his pot.
Whoops! How I typed Zimmerman for Martin is beyond me.
