Whose side does the law take in molestation charges?

Question

I heard about a woman who claims that she caught her 17 year old brother trying to molest her 5 year old son.
My friend knows the brother (not her) and we do not believe he is guilty.
The kid recently told his family that he was gay and we think that that is why she has started these accusations.

Then it turns out that she has made these kind of accusations against random people in the past - she used to tell people that a man came up and just started molesting her son at the supermarket in broad daylight.

Is it possible that this woman suffers from a disease like Munchausen Syndrome?

She is causing huge problems for her brother and even though the parents are on his side - the law might not be so reasonable.

What can be done to find out if this parent is even fit to be alone with her own son?

Could the brother go to jail without an investigation?

Answer 1

That's a really tough one. If she makes false claims, it may be because she was abused herself as a child, or perhaps she suffers from a mental illness.

Answer 2

Woever will be the guilty...
