I agree, well said, Vortex.
I think that what Sheila did by withholding crucial information (IF her story is true - personally I have doubts), is a crime in itself.
Partly because of Julie´s silence, Sheila was buried away from her children, she was buried with a heavily stained name. That is something to contemplate!
Julie was there at the funerals. Julie met the little boys´ father. Julie accepted gifts from a supposed mass murderer. Julie went on holiday with same mass murderer. Julie waited for a month to tell the truth.
IF that is the truth. If she lied and helped send an innocent man behind bars, she is even a worse person.
No matter how you look at this case, Julie is, at least WASN`T, a nice person at all!
