Die Hard 4.0....
....ring any bells? This whole scenario seems just as ridiculous as that film (which whilst fairly entertaining to watch at the lowest level, was utterly braindead action trash, devoid of any connection with reality).
What is it with America? Really.....life is NOT an action movie. Society will not melt down because a bunch of computers get hacked, it really won't and if it really will, and it's possible to launch such a completely devestating attack using *only* computer based systems, then frankly governments and Utilities companies really need to sort it out...
Oh and Duncan, I like it - although why only "specializes" and not "lazer"? Which also makes me wonder why the Americans dont spell Chinese, Chineze...
