Blaming your evil twin only works on soap operas.
And on Criminal Minds.
Not necessarily.
I know I've mentioned this before, the last time I served on a jury we got talking to the bailiff and he mentioned another trial he has helping with in the same building.
It was a rape case. The prosecution had DNA evidence. The defendant kept blaming his twin brother.
It was his third trial.
This was also a vastly entertaining episode of Columbo guest starring Martin Landau as the twins. Well worth watching if you have Netflix.
