''There's a catchphrase we use on set for the show,'' says Michael Chiklis. '''The Shield:' It's so wrong.'' With that, the Emmy winner bursts out laughing. But jokes aside, the graphic and gripping cop drama may just be the most right thing on basic cable. In season 2, now on DVD complete with audio commentaries, featurettes, and 38 deleted scenes (unrated, 12 hrs., 24 mins., 4 discs, 2003, Fox), Chiklis' Vic Mackey enters full-blown crisis mode. ''He's sort of this wild animal that's caught adrift for a while and doesn't have any mooring,'' Chiklis explains. ''And sometimes it manifests itself in the total loss of control.'' (Like, say, the time he burned off half of a drug dealer's face.) So, Michael, any hints about the upcoming season 3, which is currently filming? ''Nothing is free, my friend. Nothing is free.'' Oh, that is sooooo wrong.
