Removing a body part is also an effective way to get a pass code or pattern. If someone is willing to do you great harm to unlock your phone, I don't think it matters much what locking method you use.
And if you are not in one of those countries just politely ask for a blank white sheet of paper to sign and let them fill the rest. You will save everyone some time.
But when one has technology that works for the attacker by conveniently elimininating the mentioned problems almost completely, than your set of security features is just a pathetic lie... as well as a self-delusion.
Which, to be honest, a lot of safety and security measures and technology are to most people. ;)
