Interview with Mark Easton, BBC. Date unknown, but near the end of Tony Blair’s premiership.
Keep in mind that “hooliganism” and “anti-social behaviour” are often labels used to indicate (and reject) people from a lower socioeconomic class in Britain and that this “hooliganism” for example gets expressed in graffiti.
Of course, causing (increased) financial hardship for parents by taking any benefits away is most definitely not “in the best interest of the child”.
Tony Blair did consider graffiti “anti-social behaviour”. During a photo-op as part of his crusade, he hosed down graffiti and said that older generations of his family would have abhorred such behaviour. It then turned out that his own grandmother had been a “commie” graffiti vandal.
There probably is a work by Banksy somewhere in response to all of this.
Tony Blair also criminalized a lot of behavior that is essentially merely human behavior. That too was in nobody’s best interest and probably did nothing toward decreasing inequality in Britain.
It did not enable (more) people to flourish.
