I've been reading commentary on aviation forums like PPRuNe and the consensus amongst pilots and others in the field seems to be that "electrical glitch" is a near impossibility. Also, the report states "and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec". They wouldn't have said the switches transitioned from one position to another if they weren't certain, they would have said something like a voltage change consistent with cutoff occurred. Several people have pointed out that these are large mechanical switches that make a distinctive noise when moved and the CVR is sensitive enough that it would have picked it up. Also, it's important to note that no safety bulletins were issued to Boeing as they would have in the case of some electronics issue.

Now, when I say deliberate act, I don't necessarily mean "pilot suicide" though that is certainly a strong possibility.
