Films also have criminal masterminds ask undercover police officers "Are you a cop?", followed by a tense musical score, and a close-up shot of the cop's face...

And a "Ha, ha, just kidding, of course you're not a cop."

Crime dramas and action films tend to have an incredibly poor understanding of money, crime, policing, and Newton's laws of physics.

Significant diamonds still hold their value when resold.

It's kind of like art. Spend $5k on some locals work and you might get $50 at a garage sale later on if you're lucky. Spend $5mil on a big name and you'll likely make it back, maybe profit, when you move it. The high and low end are basically different products that function differently in the market.

It's only shmucks overpaying for mediocre diamonds that lose out.

Kind of makes you wonder if some of those films are marketing for the diamond industry.

Maybe they have a diamond shop somewhere.

I found that sequel to The Asphalt Jungle a bit less interesting than the original.
