I'm not sure it totally fits with this thread, but I watched a few different series, all with a common link, that made combined interesting viewing.
I quite like the programmes involving psychological profilers, although some of their deductive reasoning regarding suspects and crimes tests credulity, but then I saw the 'I am a killer' series on Netflix, which gives the killers version, followed by other peoples experiences, and it really flagged up how difficult such a task is in the real world.
If you get chance, watch one of the I am a Killer episodes, and make a decision in the first half on whether the killer is lying about events or not and if you would let them free, then test your decision by watching the rest of the programme.
