I am not sure I am able. I don’t support the proposed actions, and consider them highly rude and unacceptable, but I am not sure that any law-breaking will occur.
I suppose it is possible that some might try to block the Pope’s path, although is that a crime? Certainly resisting police who came to remove them from the road would be, though.
Doesn’t the pope have freedom of passage?
The whistles might drown out his speech, and might disrupt the outdoor mass. But are these crimes? Again, resisting the police who might intervene would certainly be.
"Disturbing the Peace…can that apply?
The ashes, as I understand, would be thrown at his car while others are throwing confetti. I am not sure this is crime, either.
It is an outward display of ASSAULT. It also is a misdemeanor of littering.
The lewd behavior… I am not sure why you think this would occur.
Lewd behavior has occurred at recent St. Patrick’s Day parades and have been the norm in New Orleans “Mardi Gras.”
I haven’t paid much attention to the RSM before, but I think their protest of the Pope will turn out to be similar to Move On’s General Be-Tray Us ad. It won’t advance their goals, and it will hurt their organization.
