Well, personally speaking, I get outraged about these checks because they are expensive, inefficient, often inaccurate and lead people to trust bits of paper instead of their judgement. Because abuse often takes place for years or decades before a conviction takes place, I do not believe they make children any safer - that's just lazy thinking based on government spin (sorry for any offence VintageViolet, nothing personal). Removing children from mainstream society like this runs the grave risk of damaging them through them losing the ability to trust fellow human beings, build relationships with strangers, share in community life and generally be part of a larger whole. We are ghettoising them as a result of a collective nervous breakdown about the role of children in society, and there may be very serious consequences to all of us, children included, that go well beyond the damage caused by paedophilia, violence, etc.
Plus on a personal level I take exception to the government bossing me about all the time like I am somehow potentially flawed and dangerous. I know a lot more about children than most of them, yet my voice remains unheard in all this.
That having been said, I have no objection to routine police checks in general relating to my work, it's the frequent, pedantic, intrusive and repetitive nature of CRB/VBS checks and so on I object to, especially now I am having to pay for them myself for work, and they don't seem to be tax-deductible.
For the record I don't have any truck with the age-old argument that 'if you are innocent you have nothing to fear' for two main reasons. Firstly IMO you have everything to fear because in this McCarthyesque climate you may be wrongly accused of something and have your life ruined, with little recourse. Secondly that is the exact same argument that Victorians used to justify the law allowing random women to be stopped in the street and stopped for compulsory gynaecological checks for STDs at the whim of police officers. I never thought I would see our society back there in my lifetime.
I wish they had put more resources into developing List 99 properly rather than introducing an entirely new system like something out of 1984.
