An errant tweet sent out by Spike Lee in the wake of the Trayvon Martin killing might end up being costly to the filmmaker. A Florida couple has sued because he retweeted their address in Sanford, Florida, in the mistaken belief it was George Zimmerman's, reports the Smoking Gun. Lee quickly apologized when the mistake came to light, but Elaine and David McClain, both in their 70s, say they've been subjected to harassment and death threats since. They accuse Lee of "encouraging a dangerous mob mentality." Court filings suggest they're seeking $1.2 million.
