A similar controversy erupted recently in my hometown of Pittsburgh PA, when a woman wore the 'Stop Snitchin' T-shirt to a trial. The newspapers made a big deal about it, should people be allowed to wear it into the courtrooms or not.
The essence of this matter to me is that trying to censor U.S. citizens is unconstitutional and impossible.The persons wearing such material as the "Stop Snitchin" shirt are labeling themselves as what another might interpret from the shirt's graphics.
I get the impression that the wearers of said shirts are unwilling to help the truth be known about some action (possibly against the state or other citizen) coming to light. Isn't that what the 5th amendment allows us to do? Do not our most lofty politicians and business leaders withhold knowledge of matters that they might think would bring discomfort to themselves or those they might care about?
In a perfect world we would all come clean about everything and that day will come - but it will be under the direct government of - (in my opinion) - The Kingdom of God.
