I recommend at the very least carrying a disposable camera, or pen and paper to record license plates. If they can abuse our freedoms, I can certainly utilize mine.
Unfortunately, I cannot yet afford to move away from this area. For the time being, I am stuck close enough that an explosion there may shatter my windows...Unfortunately, again, I just can't think of any sane reason these folks are video-taping and taking still shots of non-scenic views, which happen to include a federal courthouse....and, the men bring their families (women and children) with them in this task.
For what it's worth, FYI.
