Life trumps football.
Except that is the exact opposite of what happens in nearly all such cases. Instead of letting it first play out through the legal system (which is why we have a legal system), teams exact their own remedies by cutting, suspending, or otherwise separating from the person. In almost all cases, this is done by the presumption of guilt rather than as an effect of a trial, deal, or other such legal recourse.
By teams doing so, almost solely to avoid a public relations hit, they are putting football before life. Whenever people say an organizational body should hold people accountable for such matters, what they are really saying is such bodies should have the power to usurp the legal authorities, but without all of that protecting the innocent or due process nonsense.
