I saw the movie Double Jeopardy (1999) recently, and it took
the legal concept of Double Jeopardy, that of trying a suspect
twice for the same crime, and twisted it into where if a suspect
was falsely convicted and imprisoned for murder, upon release,
she is now free to commit the murder that didn't actually happen
yet without violating any laws.

The falsely convicted was informed of this from inmates when
she was in prison, and if you're familiar with Hollywood traits,
criminals always tell the truth.

Film has covered this fantastic notion before, like in the movie
The Devil's Angels (1967) where some bike gang members were
falsely accused of rape, and the dialog goes something like
"since you accused us of rape, and we didn't do it, you owe us
one rape!" Same concept!

If this stuff isn't too far fetched, than neither is the British
SciFi episode of Out Of The Unknown "Time in Advance" (1965) I
just watched from DVD. In it a futuristic society makes the
advance in the justice system by allowing prospective
criminals to halve their sentence by declaring their criminal
intentions, or "pre-crime" in advance. Completion of the
grueling sentence results in release with a license to kill.
But unlike in Double Jeopardy (1999), homicide doesn't result in a
happy ending.

Of course I had to watch an Out Of Region DVD in a
multi-region DVD player in order to see this show.
In our futuristic world of entertainment apparently only DVDs can
cross borders, but not TV channels, satellites, downloads or
streaming.
