shakedown

Extortion, especially through blackmail

What is this, a shakedown?

Four Thai police officers charged with murder in connection with the deadly shakedown of a suspected drug dealer in custody were arrested Wednesday after a video clip of the incident shared on social media caused a public furor.

A thorough search; a frisk

A trial or test period, especially of a ship or aircraft.

It was planning to use an '807' for one day only as part of a shakedown test, ahead of the fleet's formal entry to service which is currently planned for November.

An improvised bed.

All sorts of gossip floated about; one story told was that a selector, and not the youngest of that staid and sober party, was found putting his boots into his shakedown at night, and lying outside the entrance of his tent, giving careful directions to some one to call him in time for the morning mail.

"There's nowhere for me to lie down, sir," he answered, and there was in his voice a humbleness which was very distressing. -- "Don't you know anyone in the house who'll give you a shakedown?" -- "No, sir."

That tests the performance of a ship or aircraft.
