I'm prepared to give the benefit of the doubt to many cops who genuinely believe in a person's guilt and lie to get them convicted but all too often bent cops do it to cover up inefficiency, through laziness or simple incompetence.

In my case, people bent the truth for many reasons but the main motive was prestige and promotion or financial benefit to be gained by getting a high profile conviction. From promotion to medals... I feel sorry for them; Karma always kicks in eventually.

reading about this case confirms my belief that a certain Witch Hunter who was only ever the lowest rank and has exagerated his credentials while being loose with the truth, is an accident waiting to happen.
