Timecaster

Chicago, 2064: Talon Avalon is a timecaster - one of a select few peace officers who can operate a TEV, the Tachyon Emission Visualizer, which records events (most specifically, crimes) that have already happened. With crime at an all-time low, Talon has little to do except give lectures to school kids and obsess on his wife's profession as a licensed sex partner. Until one of her clients asks Talon to investigate a possible murder.

Talon Avalon is a Timecaster; a cop who is able to look back in time and view crimes that have already happened. But that was before he was framed by an alternate version of himself from another dimension. Now he's being hunted in this world, and countless parallel worlds, as the biggest mass-murderer in history.
