You are one out of three. Unpackaged isn't used, its unpackaged. Is there a reason you are choosing to be obstinate?
As for the feces and urine - if they choose to use that to assault someone, there is your crime. Prior to that, it is just a personal possession.
They weren't charged with a crime. Tell me, is a Muslim with a dynamite vest walking into a movie theater also, just carrying around his personal possessions? The inability to make subjective decisions based on deductive reasoning is a shame, a refusal to do so is a travesty.
There are many good and valid reasons to carry around a gun, a knife, a tire iron, etc. When dozens of people show up to "watch" carrying jars of feces and bushels of used tampons, only a wishful idiot doesn't know what their intent is. Do you arrest them for something they haven't done? No, but you do ask them to give up the projectiles or leave.
The problems we have in this country don't stem from preventing people from bringing large stocks of bio hazards into public places.
Well, we don't "profile" the Muslims, so that is a moot point. I'm with you on deductive reasoning, but we don't do that anymore either. Nor do we teach it.
