Real police detectives:
– Don’t give two flying hoots about a criminal’s “motive”.
– Never use “good cop/bad cop” when they’re interrogating you.
In real life, in court:
– It’s common for there to be no legible fingerprints.
– There’s usually no DNA evidence. (Unfortunately juries often don’t know this, and expect everything to be like on TV. This ignorance is a serious problem and is known as the “CSI Effect”.)
When you’re shot:
– It’s impossible for the force of the bullet to knock you off your feet, let alone fly through the air.
– A shot to the head doesn’t automatically equal instant death.
