I LOVE IT!!!!
Great idea start sending people on tours of the white house who throw up!!!
I bet if I did it, especially if I advertised for someone fitting the current Ebola profile, I'd be prosecuted for disturbing the peace, or false alarm, or creating a public panic, or somesuch. And, there'd be some justification for that.
But, on the other hand, it would make the point quite dramatically. And it's just as much free speech as those demonstrations where someone tosses around pigs' blood, or self immolates, or burns an American flag while parading the Mexican one, which the power that be leave alone
