Crowd

“Step back,” said the police officer to the curious crowd.
So, they did.
“Sit,” said the police officer.
The crowd happily sat down.
“Roll over! Speak! Shake!”
The police officer had fun with his new pet.
“Play Dead!” said the police officer.
The crowd raised their arms and started moaning for brains.
And they attacked the police officer.
Even though the police officer knew to shoot for the head and heart, there were just far too many attacking him.
So he threw his night stick and said “Fetch!”
The crowd chased the stick.
All this time, the crime went unsolved.
