The point, since you missed it, is that errors, both typographical and not, are human nature. One of an editor's most important functions is to catch them, and the frequency with which the RG posts badly flawed content suggests that the editors are often asleep at the wheel. 

Misspelling "sheriff" with two R's might be a typo, but just as likely it occurred because the writer could not spell it correctly. Either is forgivable, if regrettable, but there's no excuse for failing to use spell check.
