A defendant was on trial for murder. There was strong evidence indicating guilt, but there was no corpse. In the defense's closing statement the lawyer, knowing that his client would probably be convicted, resorted to a trick: "Ladies and gentlemen of the jury, I have a surprise for you all," the lawyer said as he looked at his watch. "Within one minute, the person presumed dead in this case will walk into this courtroom."

He looked toward the courtroom door. The jurors, somewhat stunned, all looked on eagerly. A minute passed. Nothing happened.

Finally the lawyer said, "Actually, I made up the previous statement. But you all looked on with anticipation. I therefore put it to you that there is reasonable doubt in this case as to whether anyone was killed and insist that you return a verdict of not guilty."

The jury, clearly confused, retired to deliberate. A few minutes later, the jury returned and pronounced a verdict of guilty. "But how?" inquired the lawyer. "You must have had some doubt; I saw all of you stare at the door." The jury foreman replied: "Oh, we did look, but your client didnt."

A staged wedding to bust dealers
As supposedly reported on CNN:

Undercover police, staging the wedding of "a drug kingpin's daughter", let it be known on the street that dealers were "invited" (i. e. Expected to attend).

The bride and groom were police, as was the band, bartender, and about half the guests. The band playing at the wedding was "S. P. O. C." (COPS, backwards), and the wedding went through the full ceremony, including the dancing afterward.

The long-sought dealers were arrested after the "band" took their break. The last song the band played before taking its break? "I Fought The Law, And The Law Won"
