"Rojash thinks that discrimination is perfectly acceptable if its aim is “...to alter the socio-ethnic balance in an organisation and open it to all...” Apart from the fact that there is no absolute need to enforce such a change, as far as I know (until this policy was launched, that is) recruitment to the police force was open to all. "
Marvellous NJ. First you quote only part of what I said, completely changing its meaning, and then argue against a point that I didn't make. The point I was making was if you change the scheme, and open it to all, it becomes a pointless scheme. I wasn't claiming that the scheme opens recruitment to all.
As you say, recruitment is open to all, but if you are not getting the recruits you want, you put in place a scheme to attract those that you do want. The police want more people from ethnic minorities so they target them with what is effectively an advertising policy (come and try it, see if you like it).
If you have a company with a shortage workers of a particular type, you target them in a recruitment drive. I've yet to hear anyone complain that a drive for (say) motor mechanics is unfair in that it discriminates against those of us who don't know a spanner from a wrench.
