Most people wouldn't like their dirty laundry hung out to dry
In the States you can check on almost any offence a person is convicted of. In fact the authorities make a point in notifying individuals of offenders in their area.
Making judgements / proclamations about cases when a person was not present in court is a futile endeavour. I have sat on juries and heard the prosecution and started thinking 'toss the key' yet when the defence presented their evidence a lot of the police / Crown suppositions evaporated.
Some professions are always in and out of courts, including police, medical professionals, etc. There have been cases where such practitioners were accused of crimes and harassed or driven out of their homes because the ignorant mass thought they were criminals when in fact they were expert witnesses.
Take the Sevile matter: Glad was arrested and released, but has convictions in competent courts of law (and that doesn't include VietNam); Sevile has never been deemed by a competent authority to have been proven beyond reasonable doubt to be a child molester, neither has the late MP Smith.
For all his alleged evil, Sevile's charities did good but that seems to be conveniently overlooked in this crowd-driven uproar. Mind you the police offering opinions doesn't add much to the discussion, as they are not charged with issuing opinions. Likewise the former policeman, now a self-proclaimed expert on child abuse, is, through his endless verbal diarrhoea, simply promoting his business.
Once a person has been convicted, and completed whatever sentence was awarded, they should be allowed to continue their lives without interference from do-gooders and busybodies. The job of the police is to take appropriate precautions.
Remember Profumo? He paid for his mistake and then followed it with a life of service to the community and was, I seem to remember, before his death, restored to good standing by the Queen.
If the rabble want to publish the paedophile convictions, then let everyone's criminal record be made available on-line so we can see who the thieves, shop-lifters and drunk drivers are.
