Word on the Street: It's looking more and more like Philly Mayor John Street should be worried:

Ratcheting up the federal investigation that has engulfed the mayoral election, FBI agents crisscrossed Center City yesterday to search three city agencies and the office of a lawyer who is a top political ally of Mayor Street's and has earned millions from municipal legal work.

Street's still talking a good game, saying that he's not a target -- but if he is, mind you, it's all politically motivated. What do the drums say about Sam Katz, Razor? I don't figure he has the sort of clout that could put the FBI on his side; he doesn't exactly fling his money around Washington.
