Actually, I broadly agree with Starvingartist. You do need to weigh the evidence for bias - just as you need to look at the evidence.
What actually happened on the occasion for which this hearing took place?
The defendant attempted to lead a 4-year-old girl away from her father, but was stopped within a few moments.
This is not the same as raping a 4-year-old girl. Could it have got to that point? Maybe. Did it? No. You probably can't prosecute the guy for abduction, because the child never actually left sight or care of her father. Had she done so, it would have been a different matter. There isn't much you can do except stick him on the sex-offenders register, but he's already on that.
The [REDACTED] rag in question then uses this as material to generalise from one paedophile s**t to all Afghans, in order to tout a racist, anti-immigrant message, and link it to another event for which he's already been convicted and punished. This sentence was arguably inadequate, and one might reasonably have argued for a custodial sentence in that case but, given that sex offences are often underpunished, it's probably no more disproportionate than for many other similar crimes, but that is immaterial in terms of trying this particular case.
Without knowing what was actually said in court, we have no idea how much the magistrate emphasised cultural differences over other factors, such as the actual likelihood of a conviction, given what actually happened.
One Afghan engaged in paedophile behaviour, therefore all Afghans are paedophiles? Not logical. This Afghan paedophile was not fully tried for an incident that led nowhere and was stopped very quickly, therefore Afghans have a licence to rape children? Also a logical leap.
Are parts of Afghanistan desperately poor and stuck in mediaeval social conditions, especially as regards women and children? Do parts of the country have big problems with (typically male on male) paedophilia? Are girls often married off at a very young age? Yes, but let's not overgeneralise.
I conclude that one needs to take this report with an entire pot of salt.
