I don't understand your point - the thread is about the issue in the UK - it could be completely different to the issue in other places. Your assertion that it has to be the same is, quite frankly, naive - existing crime levels, media exposure, existing acid attacks could all make the situation massively different.
Sounds to me like you are saying you have no evidence for that claim.
Then review increases Swedish acid attacks.
Focusing on just the UK as if it was some mystically isolated scenario is intentionally skewing the statistics and the discussion to allow for demographic plausible deniability.
I'm not here to assert the correctness of my position, for the record, especially since I've already pointed out one only has to look at similar cases from Germany and Sweden. I've already placed my bets on the inevitable rise of European private prisons within the next ten years.
