Political Weirdos

Well that's what I was saying, IDK how much a nuisance it actually is going to be in practice here. If it is a relatively brief record of chanting at a reasonable volume in daytime hours, that's fine. Not functionally different than a busker with an amp playing music on the street in term of noise pollution. If it is uncomfortably loud for nearby residents, fully audible from a mile away or going off in the middle of the night, then that goes beyond expression and into disturbing the peace. I know the chants are loud and disruptive (by design) in many Muslim countries. I'm not sure if they are trying to do the exact same here or if they are taking it a bit easier in this case.
