When Adam (Arnold Schwarzenegger) literally bumps into Wiley (one of the recently (re)cloned bad guys) at the police station, after a small struggle, Adam grabs Wiley from behind and snaps (with a loud crack) his neck.

Wiley's body goes limp and Adam drops him on to the ground.

Adam then bends over Wiley's now lifeless body, takes the gun out of Wiley's hand and says "...And try to stay dead this time!".

However, as Adam is taking the gun from Wiley's hand, you can clearly see that Wiley is still breathing, and quite heavily I might add.

Not bad for a dead guy...er...I mean dead clone...er...I mean...well whatever!
