1. SMOKING GUN: a piece of evidence of someone’s guilt.

The police haven’t found any smoking gun in the crime scene yet.

1. BEHIND BARS: live in prison.

The shoplifter has finally put behind bars.

1. GET AWAY WITH MURDER: doing something bad and not get punished for it.

E.g.: Rob gets away with murder because he’s charming.

1. A STEAL: something costs much less than it is really worth; a good bargain.

 I got 50% discount on my new coat. It was such a steal!

1. HIGHWAY ROBBERY / DAYLIGHT ROBBERY: something costs much more expensive than it should be, especially when you have no choice but to pay it.

The new restaurant has a very good place, but the price is simply highway robbery.

1. MAKE OUT LIKE A BANDIT: someone who’s extremely successful in a venture.

Ann’s making out like a bandit, selling expensive cars.

1. THICK AS THIEVES: people who have very close relationship. They always together and never keep secrets from each other.

Mickey and I have been as thick as thieves since we met in senior high school.
