The very 'Creepy' FEMA emergency alert 'Hack' that sounded like a Dr Seuss book and predicted the NJ Train crash.

"hazardous Material" for the entire US?

here is further explanation (the only one i can find) :

EERIE: HACKED EMERGENCY MESSAGE FORESHADOWED DEVASTATING NJ TRAIN CRASH: “WOULD YOU? COULD YOU? ON A TRAIN?”

Adding to the long list of 'concerns' this video creates one is definitely that the FEMA Emergency system can be 'hacked'

Update:

Apparently , yes the words are from "Green Eggs and Ham"
