Trump's Phoenix Rally Ripe for a Shutdown

After reading Jess Bidgood's "What to Know Ahead of Trump’s Rally in Arizona" it is apparent that Trump's rally in Phoenix tonight is ripe for a direct-action shutdown. All the elements are present: a centralized location, the Phoenix Convention Center; lots of bodies on the street participating in numerous, separate rallies/marches; and a large, twitchy police force. The only thing missing is an organized Earth First!esque monkey-wrenching action, like a street sit-down with arms interlocked in PVC pipe. I don't know if the anarchist kids of antifa do direct action other than street fighting, but now would be an excellent time to expand the repertoire.
