Manhunt!

Close the city! Stop the cars!
Folks should stay inside
While the police determine where
The bomber chose to hide.

Shut the airport! Halt the trains!
Cancel all you’ve planned;
There’s a madman on the loose,
So all should understand.

If I lived near Boston, though,
I think I’d be annoyed.
All the day’s appointments
Would instead be null and void.

Better safe than sorry
Is what’s said while he is sought,
But patience must be wearing thin
Until this guy is caught.
