There are all kinds of double standards on this issue, although there appears to be an effort to to change this of late.
Historically, photogenic children and professional parents sell papers.
A scruffy urchin or a tiny little offspring of chav parents going missing appears to raise no more concern than it would have done 150 years ago.
Non white children don't get much coverage. There's an undercurrent of if a child belongs to another culture, different rules apply.
This is never better illustrated than the en masse abduction and forced marriages of hundreds, thousands of largely Muslim teenage girls by their own families.
If even one case happened in a white, secular family the country, lead by the press, would rightly howl from the rooftops and have day to day spreads, stake outs of airports, churches etc. But these wretched Asian girls are deemed to be subject to and in peril of different laws and human rights.
It's a disgrace.
