Astra The "big deal" was not with the principle of checking but how they were proposing to do it.
Whereas CRB checks are based upon criminal records, the VBS was going to score you based on soft data.
So say you were a teacher who disciplined an unruly child and said child accused you of touching them inappropriately. The police come and its totally obvious its sour grapes and no action is taken. Well under the original VBS scheme the incident would have been recorded and scored against you.
So can you imagine said teacher going to his/her next job....oooh VBS shows there's an allegation of possible child abuse.....as their employer dare you disregard it? So there's a good chance that a totally innocent teacher's career is utterly ruined by a single baseless accusation.
Also other data (and lord knows where they'd even get this data from!) such as sexual preferences, number of partners, family history was all taken into account. Like to watch porn at home with your hubby? Better not let the government know as it would count against you.
And don't forget that the VBS system wasn't replacing CRB, it was in addition. So now to work with kids you'd have had not one but two systems to pass.
Lastly by the Labour government's own estimates, 11m would have had to be checked. That's a staggering number. Even if we assume a 99% accuracy rate (and thats a generous rate for goverment run projects!), that's 100,000 people who will be incorrectly flagged as a threat.
Still think its a backward step?
