You asked for a link to prove my assertion. I can’t vouch for the verity of the source, unfortunately.
Also, wouldn’t it be in the best interest of that neighborhood watch to disavow knowledge of Zimmerman being involved with them? If they can find even the most transient of strings to pull that avails them that opportunity, I’d think they’d be fools not to take it.
