Grin...that's what they were, for sure. I think this photo is funny as heck. The aging radical with his arms crossed probably thought he could deal with the "backwoods, hick town" cop, but it's obvious that cop wasn't about to be pushed around by some dweeb from San Francisco (or wherever).
In the meantime, the old Willie Nelson wannbe has himself craned so far out of the window of the bus that he almost looks like a cut out doll.
