If you think walking around with a rifle near a school and in public areas will not alarm people you are crazy. It is not so much the rifle is scary, but there have been actual mass shootings in and near these types of places.
The arrests are not unlawful. Common sense tells one that carrying the rifle like that will alarm people. If you do it anyway that is plenty of PC to arrest for "calculating to alarm". Once the arrest is made and prosecutors delve into it they may determine that it is appropriate for charges to be dropped, or not.
I realize they are trying to educate people, but doing so carries the fact that you WILL alarm people and the police WILL act. If you can afford the consequence then knock yourself out.
Perhaps. I intended to write in generalities as my thesis.You have said many times that it's not good to condemn without all the details. I think this is a case where you might be doing just that.
I want to debate whether or not the fact that people will be alarmed has anything to do with "intent to alarm" but have a feeling I would not fair well against our resident expert on Texas laws.
