This is the wrong question really and is slanted in its representation in my opinion as are most of these "polls."
Of course Tillman should have freedom to be employed in any legal capacity after having gone through the legal process just like anyone else for any given civil and/or criminal matter. No employer however is free from the stigma that comes with hiring ANY controversial figure though.
But ought Tillman be guilty or not guilty in the Court of Public Opinion of which we all are members?
And if still guilty, the open question is when is Tillman really forgiven such that most of the public can move on?
Sometimes there is no answer but "in due time" anyway, and no one knows when that is.
Note that forgiveness is not the same as most of the public merely forgetting the matter as would be the case with a Grey Cup or for other reasons such other far more overshadowing and pertinent news beyond football like natural disaster, terrorism, et cetera.
