part of the reason that old people will line up to get arrested at protests is they're retired so they don't fear a criminal record. but i think maybe another part of it is like, once you're old, authority is no longer a bunch of grownups who have power over you, most if not all of the people arresting you, trying you, sentencing you, and so on, are younger than you are. so, if you're old, you can look down your nose at them, perhaps rightly, as a bunch of stupid babies who don't know anything
