So you think you have computer security problems. What if you were responsible for the security of computers the police and military would really like to seize?
Apparently in a recent raid on the FARC, Colombian authorities seized some 15 laptops and some 100 USB memory sticks. The authorities would like to see what's on them.
The story suggests but does not flat out say that the storage media were encrypted. Given the circumstances and the ready availability of encryption, this is a reasonable assumption.
With any well written and properly deployed encryption setup, lose the keys and you've lost your data. Unless there's a back door placed there by the authors of the software, that is. And how do you know there's no back door? Use the source, Luke.
Assuming the FARC have IT folks capable of the above reasoning, which operating system is almost certainly not on those laptops?
