"Tonight we visited the home of Peter McCausland, Chairman and CEO of Airgas, Inc.

Airgas has made the poor decision of holding GlaxoSmithKline President David M. Stout on their board of directors. Hopefully they will rethink that decision soon.

Two cars, including a new porsche, were covered in paint stripper, and McCauslands house and property were spray-painted. Kick Stout off your board or your company will continue to be targeted."
