no, i don't know their motives. that's what i'm curious about.
how many times have you wandered into a closed courthouse at 2am?
Back up any more you're going to fall off that limb you climbed out on. And I don't go to a court house without a summons, usually for jury duty, but I was called as a witness once.
so you can admit that it's at least odd that they found themselves entering a closed courthouse at 2am, right?
so why would they do that? did the courthouse have a great mural they wanted to see?
it's just damn peculiar, and although they may not have broken any laws it does seem fairly certain that they weren't there for any normal reason.
