Great White Sighting Won't Close Mass. Beaches Predator no threat to public safety, officials say By Nick McMaster, Newser Staff Posted Jun 28, 2010 2:45 PM CDT 15 comments Comments Great White Shark (c) (Newser) – Dun-dun, dun-dun: Massachusetts isn't about to let a measly 200-pound juvenile great white shark close its beaches. The beast was caught and released 20 miles offshore, and "we don’t believe it is a threat to public safety,'' a top environmental official tells the Boston Globe. "White sharks have been here, and they will continue to be here.'' The state's one safety precaution? Avoid swimming with pods of seals.
