"I hesitate to use the term "over-representation"
Over-representation of what?
Do you mean employers who pay next to nothing wages to their domestic staff and threaten to send their "employees" back to where they came from if they don't comply.
Or sex trafficers bringing girls into the country on the pretext of giving them legitimate work.
Or the sweat labour that has existed for centuries in Britain in the clothing and catering industries
Or the building workers working the lump.
Or simply the many thousands of employers who don't register their employees and totally ignore the legal minimum wage, safety regulations and general employment laws.
Where else can you cite Travellers holding employees against their will and forcing them to work - all the above mentioned are well established indigenous practices.
Given your past ventures you would be well advised to steer clear of "over-representation.
I do hope you aren't going to make this another one of your 'missions'!!
As for sympathy for the victims; the best way to show that is not in mealy mouthed platitudes, but to deal with it for what it is, a crime by ruthless criminals; it is totaly irrellevant that in this case they happen to be Travellers, and the cynical use of this only diverts away from it being righted and prevented from happening again.
