Yep - what does the money have to do with it other than more class warfare in the mind of the Martin clan lawyer. Any bets on whether he tries to depict George as a wealthy individual with a siver spoon in his mouth and a penchant for exercising the power of his wealth to kill darling young Black boys. Can I say "boys" or is that racist too?
The only issue that could be raised by the prosecution regarding this money would be, did the defendant mislead the court about his financial status? And as has already been pointed out, Zimmerman had been in jail, and likely had no idea at the time of his bond hearing how much money had accumulated.
