strawman!
It is a logical extension of the same argument. Are you aware of Dr Shipman?
There is no logical reason to think the state can run a prison better than private owners. Further if a private operator is no good then their contract can be revoked/not renewed. This is what happens with the train operators.
The public sector is an horrendously expensive joke in the UK. It is not hard to see why this has happened (though ppp's are a disgrace)
BTW if you think it is a straw man why do both major parties in the UK accept private prisons operated for profit though neither will coutenance new private for profit schools?
Hopelessly inconsistent.
