After the incident they are shrugging it off. My guess is that they were trying their luck; had they found anything on his laptop which they could use against him - like any of the leaked documents - who knows where he would be detained right now.
My guess is that it was like the bully who shoulder-checks you when you're walking by them in the hallway, and who just keeps on walking.
I think it's like a teacher checking your bag (under the pretence of "finding drugs") in order to confiscate your camera that contains incriminating pictures of them.
I think it's more aggressive and invasive than that. Maybe if the pictures were of the superintendent and their paramour. Maybe.
