TONIGHT'S MIGHT-SEES

"Law & Order" season opener, 9 p.m., NBC. In the best "Law & Order" tradition, this hour will tug you on both sides. Grown men were in a deadly fist fight. This was stupid, but was it a crime — and under which law? There's no easy answer. Before the hour ends, McCoy (Sam Waterston) has heard a fierce argument from Lupo (Jeremy Sisto) and several quiet ones from Cutter (Linus Roache).

"Medal of Honor," 9 p.m., PBS. There are great stories here. We meet Hershel Williams, the undersized corporal who kept crawling back for more flamethrowers. And Tibor Rubin, who survived both the Holocaust and an anti-Semitic Korean War sergeant. There's Drew Dix in the Tet offensive, rescuing civilians and capturing 20 prisoners. And Charles Liteky, a chaplain who carried 23 wounded men to safety, later returning his medal in protest. Despite so-so narration, this is a fascinating film.

OF NOTE

"Dancing With the Stars," 7 p.m., ABC. The results show, usually on Tuesdays, was delayed a day because of the election. "Pushing Daisies" rests for a week; "Private Practice" gets a stronger lead-in.

"Knight Rider," 7 p.m., NBC. Mike and Sarah are stuck in a plane, trying to keep KITT from self-destructing.

"Life," 8 p.m., NBC. This show has had trouble getting noticed. Tonight's hour strains credibility, offering a support group for mega-millionaires. Still, the main character (played by Damian Lewis) is interesting.

"Private Practice," 8:02 p.m., ABC. As the clinic's new leader, Addison takes a chance that puts the clinic in more danger.

"Dirty Sexy Money," 9:02 p.m., ABC. During Letitia's trial, Nick finds a dark secret about Nola Lyons, the prosecutor.
