Today a San Diego jury acquitted 40 year old Jeff Olson on 13 counts  of  vandalism and he was also facing a 13-thousand dollars fine. It  took  the jury less than five hours to arrive at their decison. It's  the case  of a San Diego, California artist who was prosecuted for  vandalism,  after writing anti-Bank messages on public side walks, using chalk.   Olson's anti-bank messages included one that read:  "No Thanks, Big  Banks" and another that read: "Shame on Bank of America."  Over the  weekend, in a protest dubbed "Chalk-U-Pie" dozens of supporters drew  their own colorful messages in chalk, including the phrase "This is NOT  vandalism!". At the end of the ordeal, Olson said  he was relieved it  was all over.
