Siren of the police cars

He knows himself as a mere academic person with  scientific concerns ! he never attends in political conflicts…he pays no attention to social and political discussions…he believes these r just some kind of rabish. Last night , while crossing ther road he hears the sound of siren police cars for protecting the charectors….he just sits there…on the pavement an cries for half an hour!...who Is he actually? A simple unknown researcher or a recently  born revolutionist?
