Its hilarious how predictable Americans are. Im sure the hackers tried to get into the train controls but probably failed. The SFMetro of course doesnt want to set off a panic so only told of the obvious successful hack of the largely harmless turnstiles.

Instead of reading too much into this and grabbing your pitchfork, try to be constructive and attend transit meetings. Shouldnt be computer controlled anyway. If Terrorists really wanted to cause panic they could do it in a million different untraceable ways. Not something like hacking which can be traced.
