Why Do They Hate Buses?

More bus burnings continue in the Paris suburbs. As Blog of the Week Confederate Yankee notes, these outrages are perpetrated by “The Undescribables.” Notwithstanding the many witnesses to the crimes, news accounts never say anything about the perpetrators–except, of course, that they are “youths.” Seems like they’d be easier to catch with a description.
Meanwhile, the French government says it will step up “transport security.” Maybe they intend to follow our example and ban liquids and gels on buses. Somehow, though, I’m not sure that’s the right way to think about the problem.
