Why Does Mr. Knowitall Delete Threads when It Becomes Obvious He Doesn't Know It All

Consider the recent traffic violations thread in which he implied that a California Red Light Camera Citation would be a zero point violation. That's never been the case in CA and when I pointed that out, my post as well as his implying the incorrect information was deleted. Hmmm. Oh, I think I have it figured out. It became and "argument" and that's not the place for those. So, it wasn't to keep Mr. K from looking like he doesn't know it all after all. Interestingly, he's perfectly happy to point out when anybody else gets anything wrong.
