[Sticks]

Sometimes the police will know that certain people are guilty as sin, but due to witness intimmidation, no one in their right mind would testify (similar to where I live), or the police would have to reveal sources, so they have to drop the matter

In this case there is "insufficient evidence" for a conviction. It is not the same thing as saying someone is innocent. Often under our system, the guilty go free.

One of the tricks abusers use to keep their victims quiet is to say that no one will believe them, and for a long time nobody listened.

Defence lawyers are skilled in ripping a child's testermony to shreds. If there client is guilty, who cares, they are batting for his team.

Knowing this, and in order to protect the child, the CPS may advice that the case be dropped.

Even when someone does testify, sometime the courts let them off with a very light sentence.

None of us are privy to the Matthew Kelly case, but as far as I am aware, they have not charged the original complainent with wasting police time, like they did that women who falsely accused the Hamiltons.
