Did a google search for the "Zimmerman Defense Fund". Doesn't look to me like Zimmer has personal access to the money.
" This is the only official website for the George Zimmerman Legal Defense Fund. The money donated here will be used for George Zimmerman's ongoing living expenses, legal costs, and fees for this matter. The funds are being administered by a third-party administrator, who has a background as a former IRS agent, a Certified Public Accountant, and great experience in dealing with Chapter 7 bankruptcy trustee matters.
We have chosen to use PayPal to collect donations because they offer secure transactions, they have a strong reputation for online monetary transactions, and they are a trusted third-party.
The personal information that is collected as part of your donation process will be kept strictly confidential."
