How do I start a picket line?

Question

I want to picket in front of the Immigration Court in protest in a few weeks.

Question: Besides getting the people together, how the heck does one go about starting a picket line?

Do I have to get a license? Or can we just show up and picket?

Answer 1

I don't think you need permission as long as you are obeying the law, and not impeding pedestrian traffic, shouting profanities or generally disturbing the peace.  If you are an American, don't you people have the right to peaceful assembly?
