This story reminds me of one, several years back; Denny's restaurants
(a nationwide franchise)
Allegedly: Denny's was accused of racism, and had pending lawsuits, for not serving blacks, making them wait for service, etc.
The situation was exploited in the media, just like the one with Prof Gates.
Over time, false accusations spread nationwide, with people trying to extort anything from a free meal, to money.
Denny's finally wised up and installed hidden cameras.
When the next false accusation of racism and lawsuit was threatened, Denny's produced the video tape, and the accusations, and lawsuits miraculously stopped.
It's too bad, behavior like this ruins it for the people that are truly victimized.
