Here's the deal.  Constitution protects citizen.  If the chief broke a law that has nothing to do with the constitution.  Did the government violated the chief's rights while they were putting the case together.  Maybe they (government) violated one of his rights.  Did they (government) search his home without a warrant.  Did they (government) question him without his lawyer being present.  Did they (government) wire tap his telephone. If the chief stole somebodies lunch money and he got caught and was given his rights at least the first 10 amendments then he is toast.  Employment rights are usually contractual.  Unless their is an age, race, color, religion, gender and a few other issues (discrimination) he has a civil case.  There is no constitutional issue.  This conversation is over.  Thanks and have a nice evening.
