I never said that they had no friends... friends are not always in a position where they can help you! I've seen a person get jumped and when his friends tried to help they were out numbered! Anyone planning to jump someone is going to attempt to scope out the person and who he's with before they jump you!
Or is that only here in Miami?
I recall vividly at the Inferno lounge night club in Ft. Lauderdale my best friend and his cousin were jumped in the mens room by four guys...what they didn't know was they had another cousin with them that had a gun (yes a gun inside the club) end of the story four guys laying on the mens room floor with bullets in them!
Again, like I said you never know what the person may have or whose with them!
