I think he is just very annoying and his 'point' about people being filmed on surveillance CCTV, all the time, is fallacious. I thought everyone handled him with more respect than he deserved. One has an expectation of being filmed on surveillance CCTV while in a public place, not in a private classroom. Where surveillance CCTV does operate on private premises, there are usually warning signs. Plus, most surveillance CCTV cameras do not record audio.
