@HJ - The powers of the CCC in terms of questioning are significant, and in my view an absolute outrage. The powers are designed to allow the CCC to investigate serious crimes, but are being misused mainly for the purpose of gaining evidence in criminal proceedings. They force people to come in, answer questions and essentially waive their right to silence. They seem to be moving towards a trend of going after high profile members of the community, rather than concentrating solely on serious crimes.
The whole thing brings into sharp focus the costs of allowing governments to enact laws for the so called purpose of helping fight crime. What we are left with is the CCC, a law unto themselves using extreme powers to gather evidence against a high profile footballer for what I would imagine are fairly minor crimes.
