Okay, every crime TV show ever, it takes WAY longer than that to strangle someone. Even if you’re directly cutting off bloodflow to the brain instead of just preventing them from breathing, it takes a couple minutes, bare minimum, to kill someone. 30 seconds won’t do it.

I literally just held my breath for longer than this guy in this TV show strangled someone for to kill them. Without significant difficulty. 

Yeah, I know you can’t make a good show with like 4 minutes of someone being strangled. Very few people want to watch that. So, TV people really gotta come up with better ways of killing people than strangulation.
