I think the key there is random citizen. That could be you or me, right?
So you and I should be afraid, all the time, of authority, because. just because.
And what IS the point of that? There pretty much has to be one. I'm not claiming precise knowledge of what that is, but the general goal seems to be a compliant populace who choose not to use the rights that we have to shake things up.
That seems to be a bit different than past generations. They did nasty things in our name, but at least they lied about it rather than setting a legal precedent with it.
