Well you can go back in time on the way back machine and check out Homicide: Life on the Street, it was the prototype for The Wire. It aired on NBC back in the nineties and was rather edgy for network TV of the day. Not near as edgy as the Wire mind you.
Now if you want to get off the wall, check out Dexter every Sunday night on Movie Central at 8. It’s kind of like CSI if Grissom had gone off the deep end and started killing perps in his spare time.
If you’re feeling patriotic, the CBC is running a half decent show on Tuesday’s at nine called Intelligence. It’s showing a bit of promise, but is occassionally threatening to weigh itself down with too many sub plots.
