Speculation

The Arkansas Times blog republishes an article from the right-wing Boston Herald so you don't have to give the Herald any traffic. The lede:

GASSVILLE, Ark. - The neo-Nazi teen who attacked patrons of a New Bedford gay bar with a hatchet and pistol was only a short drive from two Arkansas white supremacist groups known to recruit in Massachusetts when he had his deadly shootout with police.

All here.
UPDATE: He left a note. At some point, presumably, we'll find out what's in it.
