Do you have a source for the antifa claims (especially the discord)? I tried to run this down yesterday and sort of hit a brick wall. Looks like most of the confusion was the ATF misinterpreting the arrows on the casing.

If antifa IS involved, that unlocks a whole new world of possible action against them, which is important because the Portland police refuse to do their jobs and Tina Kotek won't allow Trump to bring in the Guard.
