It was about this Asian kid, living in some American city and adopted by a cop, I think, and was a martial artist. I think there was one scene where he fought back against another kid who was giving him trouble, who was the son of his adopted father's (or a previous or following guardian) boss, and was said to have stitches in his head. Anyone know what show this was? There was also a scene where the cop kept his cuffs in the fridge, and the kid moved it from there, or something like that.
I think you're thinking of Sidekicks with Gil Gerard. The part about the cuffs in the fridge rings a bell. It followed a tv movie The Last Electric Knight which was actually an episode of The Wonderful World of Disney.
