Blight a career for life

In the UK, even an official warning from thugs to a teenager can blight a career for life.

It doesn't surprise me that this happens more often to blacks. Once there is a repressive system, little details where someone has discretion are easily warped into systemic racism.

The UK seems to be egregious in this regard. In the US, according to my understanding, even the criminal convictions of minors are usually erased from their records.
