The CSA is an expensive, inefficient department that is antiquated and not able to cope with the requirements of those that needs its help. Give it more powers, make it a fairer system or get rid.
There is a system to be played with the CSA and if you know how to play it you can get away with it. They have NO power to deal with those who refuse to co-operate. For those who do co-operate they sting you for it – there is just no fairness. They are mightily inefficient – too many errors are made. Either give the CSA the powers to make it fairer or scrap it.
