Federal prosecutors are treating President Donald Trump’s personal attorney Michael Cohen like he’s a lawyer for the mob, say seasoned white-collar defense attorneys describing the raid on Cohen’s home, office and hotel room.

Lawyers told the Daily Beast that raiding attorneys’ offices isn’t unheard of. But it’s generally used for lawyers who work with alleged members of organized crime, or for lawyers who are involved themselves in elaborate criminal schemes. “It’s a tactic generally used against organized crime, against very serious, very serious criminals and lawyers who are operating outside of the protections of the law,” said attorney Alan Dershowitz, a frequent critic of special counsel Robert Mueller’s tactics.
