Gonna be tricky when people peaceably assemble to block all the entrances and exists of every building ICE operates out of.

  Republicans in Washington state have proposed a plan to 
  reclassify as a felony civil disobedience protests that 
  are deemed “economic terrorism.”

Similar laws are being proposed in multiple states. You can protest, but don't imagine you're immune from prosecution by a sufficiently annoyed DA.

Oh I'm well aware of that. And I predict the more heavy-handed the attempts to restrict protest become, the more people will come out to oppose them.

If you're blocking an enteance or exit that is not being peaceful and does result in arrest.

Why convince a crowd? They can simply visit you at home or work a day after the protest, device location tracking and face recognition works well enough and they don't need to detain everyone, just enough for deterrence to work.
