"My foe but I am shocked and saddened. Even though we didn't see eye to eye he deserves our respect RIP Noel Van Swol". Actor and activist Mark Ruffalo pays tribute to a rival protester who died in a car crash on Monday (15Oct12). Van Swol had been a big supporter and campaigner for drilling for natural gas - something The Avengers star is strongly opposed to.
