With the RNC rapidly approaching, Minneapolis cops have gone nuts. So far there have been at least two reported incidents with cops jumping out of vans and seizing photographers and equipment, but not actually arresting them in at least one case.
Regardless of the ethical issues its not a matter of principal at this point. It's a matter of not getting your ass kicked over something stupid while everyone gets accused of being a would be terrorist. No need to turn a simple trespassing charge into a Homeland Security matter.
Missions will resume after the RNC has come and gone. That is all.
