Riddle

A woman proves her sister murdered her husband, yet the sister goes unpunished. Why?

Choose an answer

A.The sister had diplomatic immunity
B.It was self-defense
C.There wasn't enough evidence
D.The sisters are Siamese twins.
Hint: It's a 5-word phrase with 25 letters, starting with "T".

Answer

The sisters are Siamese twins.

Why this is the answer

As conjoined twins, punishing one sister would unavoidably punish the innocent twin too, so authorities cannot act.
