Wish we had the audio evidence of the school calling the cops and asking them to come arrest a kid because they don't like his t-shirt.
Again, they called because he was arguing. However I'd like to see evidence that he wasn't arguing about that shirt...
The shirt was the root cause, even if you pretend to be incapable of understanding what a root cause is. About this time you would normally be telling somebody making that kind of stupid argument that they were "thick"... I don't believe you are incapable of understanding, only that you are incapable of admitting you understand, when it goes against your political view, regardless of what may be right.
