My understanding is that in many historical examples of civil disobedience there was often an prior understanding between the protesters and the police as to what was going to happen. In a sense, it was scripted.
I'm not going to try to justify the police actions in Austin -- I don't know the details, but it seems to me that taking a large number of people into custody with no "script" and with the people not ready to be detained is probably quite hazardous, stressful, and ripe for something to go very wrong.
> Folks, this concept isn't that difficult, and there seem to be a bunch of comments arguing about what civil disobedience really is, as if we didn't have hundreds of years of examples and jurisprudence to go by.
I think what I've learned it discussing this is that in fact most people don't understand the philosophy of civil disobedience. Most people seem use the term to mean "breaking things, intimidating people, and baiting the police to draw attention to a just cause". And there is a unexplained rule that determines when the cause is "just" enough to excuse committing the crime that draws the attention.
