Tell me a joke about police officers

A man calls the police

A man calls the police and says, "There's a burglar in my house!" The dispatcher says, "I'm sorry, sir, all our units are busy. We'll send someone when we can."

A few minutes later, the man calls back and says, "Never mind, I just shot him."

Within two minutes, three police cars, a SWAT team, and a helicopter show up. A dozen officers rush out of their vehicles and into the house. They find the burglar and arrest him.

A bewildered officer asks the man, "You said you shot him?"

The man smiles slyly and replies, "I thought you said you couldn't come."
