This looks really bad
I agree with Radley Balko here; I really hope there's more to this case than I've yet seen, because otherwise it looks really bad:
We’re going on a press account of one side of a lawsuit, here. So it’s possible—and I would hope—that there are some important details missing.
Otherwise, a police mistake leads to an innocent 12-year-old getting violently snatched up and roughed up by a group of plainclothes cops jumping out of a van . . . and they charge her for resisting?
