Why are people crying about Ben Rothlisburger not being charged?

There was not enough proof for Ben Rothlisburger to be charged. Therefore it could not be proven that he was guilty of any wrong doing. Why are people acting like they know exactly what happened? Sports columnist, and basically everyone else is demanding that he be punished. I don’t care if it is the second time. There was no proof on either of the acussations. Why don’t just leave him alone?
