>but I think you're obviously right
Did you read all the research presented in the article and here in the comments and come up with that conclusion, or are you just talking out of your ass?
What if they didn't have the password? This is a real life example. I'm going to use an example. This lady was stopped on an airplane because she was carrying explosives. Her husband packed her bags and she didn't know she was carrying them. What if it was a really important laptop? Would you torture her? Would you risk giving her a lifetime of mental and physical scars because you thought she had a password she didn't even have?
>In that situation, it will work.
You sure about that? Some people would rather be a martyr and die. Examples are all around.
Waterboarding can cause death by the way.
