Highland Park is a town of 30,000 and is 83% White. All of the paradegoers I saw were also White.
** UPDATE **
The Chicago Tribune has published a preliminary description of the shooter:
Long haired White guy on the fourth of July shooting middle American White people at a patriotic parade? You know what I am thinking...
** UPDATE 2 **
Big Country has weighed in with a link to a video, embedded below. Now that I heard the gunfire I agree it sounds more like an AK than an AR.
** UPDATE 3 **
Things are moving at light speed. We have a name....Robert ‘Bobby’ E Crimo III. First pics I saw, unverified, look like a loser with face tats, we will see
** UPDATE 4 **
Pics are out, guy looks like a leftist loser.
