Just FYI, the author of this post has posted as a police diversion, with the intention of concentrating and segregating "rock throwing anarchists" away from the other planned M19 events.
While perhaps well intentioned (it's been posited that black bloc direct action tactics are not congruent w/ the rest of what's been planned for M19) I think this action was idiotic on the part of the author as it will likely result in a slew of folks showing up, with no organizer present and thus no direction or cohesive basis and a consequent increased chance of arrest.
I hereby encourage anyone who's planning to attend to have a preconceived route and "point of intervention" list in hand so as to reroute this potential disaster.
It might, I'll posit, be proper to integrate ourselves into one or another of the M19 actions, as I personally am unconvinced that they're entirely incongruent w/ militant direct action.

In love and struggle.
