how do you know this is being done by anarchists? I'd guess the chances are just as good if not better that it is being done by a bunch of right wing white supremacists or tea partiers.

They did have a prime suspect for the DC attacks, but he killed himself, so we'll never know.

"I'd guess the chances are just as good if not better that it is being done by a bunch of right wing white supremacists or tea partiers."

Let's look at the past few years of attacks and violence Randy:
Occutard destruction in the parks and on marches
Anarchists threatening and damaging businesses
Radical muslim attempts to blow up Christians
Gay gang attacks 'one man, one woman marriage' Christian church

I don't recall any tea party / right wing attacks or threats in Portland for a very long time. Most of the trouble has been from the so-called peace loving leftists.

Ha! He's an Occutard! He's one of you guys! Christopher Lee Carlson
