Hard times call for hard decisions. I get that Free Speech is limited by incitement etc. It is less clear for things like this. Something that is on target to kill fewer people than a dozen other causes...not sure that justifies blocking protests.
Don't get me wrong. I'm sitting in my house posting on the internet, obeying the authorities, even if the authorities don't have the power to order to me to obey, I choose too. And, probably people should give the benefit of the doubt to the authorities, at least for now. But, I'm also hard pressed to say any of those people protesting should be put in jail. I wouldn't do what they are doing. But, I can't say they are wrong to do what they were doing. History will answer that question.
