This is under the category of "Things I larned on Modoweiss" What is the legal standing on this issue in other places?
never herd of anything like this in Australian law (though bells would know better). there have been laws restricting specific protests (like the struck down World Youth Day laws and the APEC laws) but the closest example to this i can think of would be the preemptive visa refusal for people asaociated with the nutjob fred phelps who threatened to protest at heath leadures funeral (though i wish they had let him in then charged the basted under antidiscrimitation and inciting vilonce laws)
