I guess I would hope it takes more then that to rise to the level of obstruction.
Additionally, you have to prove intent, and unless the judge was careless, I doubt they will ever be able to do that. I'd bet the prosecution knows this, I don't think they expect the charges to stick. It seems this arrest was done to send a message.
More evidence of that is that typically in this kind of case they would invite her to show up somewhere to accept process, not be arrested like a common criminal.
