It's not nearly that simple. You can essentially print an opinion based only in fact, both by picking carefully which stories you cover, and also which details of which story you choose to report. It's completely possible to frame the exact same story as either left wing or right wing using only facts.

If you want recent proof, look at that debacle with that Toledo kid. Some reported police shoot an armed thug, some report police shoot an unarmed kid. The video proof shows neither side is telling the whole truth.
