1) I had a similar question regarding the fact that we are (broadly) defined in a restraining order and thus could have implications on our CPL or gun purchases. But it's only temporary. It will be resolved in court one way or another.
2) A peaceful picket is up to you, you are of course free to do so. But I think our point is very well known. At this stage, it's most important now that the court takes our point. I think it's best to lay low for a while. I think the library has a good case suggesting they are an autonomous authority but I think we have a better case since their board is appointed by local governments, they are funded by local government tax money, they are in a building owned by a local government, and they provide a public service. Their other argument is it's a school, which is flawed since we can OC with a CPL. As long as the judge properly interprets the law, we will win.
3) Carrying a knife, like carrying a long gun, is probably 100% legal (and for the sake of liberty, I'm all for it), but its more difficult to argue practicality lugging around a long gun or a sword (and I'm not suggesting one would need a 'reason' anyway, but for whatever reason, people are typically more comfortable around a holstered pistol than a shouldered long gun). In other words, I feel you are free to do it and would support you, but others may not.
