I saw the episode where the Black Hat was trying to erase their identity by blowing up the Internet. There were so many things wrong with the plot that I'm afraid for our civilization if this show has good ratings.
The idea you can take out the Internet by destroying one cable may work if you're in the Middle East and all you have is one cable, but the whole point of the Internet is there is no single point of failure!
The bomber blows up a server that stored the data he wants to disappear. Yeah, like there's no such thing as offsite backups...
Then came the "fact" that network routers store the messages that traverse the Internet. Huh? All they need to do is plug a monitor into the router and display all the emails that went through, finding the one single email that incriminates the Mad Bomber.
But wait, there's another bomb, about a cubic foot of C4, more than enough to bring down the building they're in and the neighboring buildings, too. Oh, look, they're remodeling the Network Router room and they left some drywall joint compound, which, when mixed with salt or sugar (I missed what the mystery ingredient was) makes a substance so strong it will absorb the majority of the explosion, saving the building.
But even though the file is destroyed, there's one Scorpion with a photographic memory and he can recite word for word the content of the incriminating email. That should be perfectly admissible in the court of law on their version of Earth...
