"...see if your opinion is representative."
Nah, there's no point. I know it's not, but it's still the way I feel about it. That's the joy of living in a democracy.
"Ultimately you are saying everyone should be viewed as a potential criminal... This is a failed society"
Yes that's what I'm saying, and yes I would say it's already a failed society. In fact all societies are flawed to a degree and always will be. My argument is that we have to accept that and do our best to mitigate the effects of it.
"But if you don't commit crimes what benefit is that?"
Well, you know, I wasn't aiming for it to just be me. I don't think anyone is asking for a voluntary system, are they? However, I represent one of 50-60 million British citizens who are, as I already said, potential criminals. For every million 'innocent' people, some number will go on to offend. When you're talking about laws for society, you have to look at things in terms of statistics because it's impossible to make informed judgments about individuals. You're suggesting that we trust random, non-specific members of society to not commit crimes even when we have the statistics to prove that X% of 'innocent', i.e. never-convicted citizens will offend at some point. How can we trust society when we have the facts to prove that it isn't trustworthy?
"This is the core of 'innocent unless proven guilty'."
And I agree with this principle entirely. I don't agree that keeping a record of my DNA indicates that I'm guilty of anything. Only that I'm one of a very large group which includes people who are guilty.
"does it make it friendlier if I accused you of not being a 'likely' rapist"
You actually said you 'guessed' I was a rapist. The fact is, you don't know if I am or not. Statistically, and from the perspective of what you know about me (incidentally, not hugely more or less than the government probably knows about me) there's probably a certain (small) chance that I might be. Do you trust me not to be? I don't see any reason why either you or the government should assume that I'm not.
I'd be singing a different song if this was going to restrict us in any way, but it doesn't. It's an purely reactionary system, designed to aid in the prosecution not prevention of crime (the latter only in the form of a deterrent). We would retain all our freedoms to do what we like (including raping, if that's what we want to do). In almost all cases it would have no effect on us whatsoever until such time as we committed a crime. To me it's in refreshing contrast to the likes of DRM which actually stop people from doing things which *might* include illegal activity. But I digress...
Clearly there's a difference of opinion here (!!) about the value of privacy. I think it's overrated.
PS, I'm not a rapist ;)
