Probably ok outside and a distance away from when and where the protected parties are entering and exiting.
Going inside and disrupting is not allowed.
Remember when code pink went into a government meeting in disguise then revealed themselves and had simulated blood on their hands and one of them actually seared some on an elected official.
They were escorted out but IIRC not charged with any heavy crime.
They did similar things also and reported many times on FR

I remember that.
The official was Condoleezza Rice, if I recall correctly.
The game is played like this: Code Pinko makes themselves obnoxious. The police “arrest” them. Let them go 20 minutes later.
The police are in on it. I saw this with my own eyes in front of the Washington Hilton one WHCA FReep.
