So here's the funny part: it was only after that that I thought to Google him, and what I found out is that he used to be a cop in Dearborn but was fired, and later sued to claim his free speech had been violated, because the official reason for his firing was that he insisted on writing his 7s in the "European" style, with the little crossbar, after having been ordered to knock it off. Ha! Isn't that a hoot? I mean, that's not even really why they wanted to fire him, but just the direct order he disobeyed that they could cite that got the ball rolling. But still. Read all about it here, in legal detail.
He may have wasted my time, and his particular historical kookiness is maybe a sign he's trouble in general, but part of me is sympathetic that he wanted to make his 7s the way he wanted to make his 7s, and sorta tried to assert some fundamental right that way (while there was also more to it, yeah, but that part's not as funny). I don't just say that cuz I like to cross my 7s. Tho I do.
