A train carriage containing controlled nuclear materials was stolen
in Cincinnati today. Its whereabouts are unknown.
The incident occurred on the downtown train line, which runs from
Covington and Ashland stations.
In an email to Ohio news outlets, the U.S. Department of Energy
said it is working with the Federal Railroad Administration to find
the thief.
“The theft of this nuclear material will have significant negative
consequences on public and environmental health, our workforce
and the economy of our nation,” said Tom Hicks, the U.S. Energy
Secretary, in a statement. “Our top priority is to secure the theft and
ensure it doesn’t happen again.”

Shakespeare:
O, if you were a feeble sight, the courtesy of your law,
Your sight and several breath, will wear the gods
With his heads, and my hands are wonder'd at the deeds,
So drop upon your lordship's head, and your opinion
Shall be against your honour
