this is very, very difficult to stop.es tucker: how would you even go about trying to stop it at the law enforcement level? i don t want to come on your show and just complain. there is a way to at least hopefully make a dent. i think the country would be astounded if they realized me being a former federal agent and a former new york city police officer, how few people of interest are under active physical surveillance. i m a libertarian at heart. i think we wasted a lot of time on mass data collection from people who have nothing to do with anything. we ve fallen in love with signal intelligence, collecting emails and social media and we fallen out of love with old school shaking of the trees and communities. an old expression for going into communities in developing high-quality investigative sources.in it s how we broke up the mob, it s how we can do it against this radical islamic ideology. we are never going to stop this
