Block from stolen topic

HI ALL :)
Hi all guys i want to ask or to search somebody who now if exist a program what block the power button on the phone.
now i will explain.
I think if its a method to block the power button because,if in lockscreen you block the power button
(only for phones what have non-removable battery)
with some program,the thief can power off it and you will bee able to find it with program like androidlost.
i think this is a good method to counteract mobile stolen. :good:
p.s: sorry for my bad English :D
i'm LG G2 user.
