Opposition Spokesman on Justice, Senator Mark Golding, is supporting calls for witness statements to be video recorded.
His support follows the revelations that the key witness in the X6 murder case, changed the statement he gave the police in July, 2011.
He says the case shows up several weaknesses in the justice system, namely how cases are prepared and the length of time it takes for cases to reach trial.
He says this may result in witnesses being vulnerable to bribery and intimidation.
On Friday the key witness, taxi driver Wayne Wright’s inconsistent statements led to the case collapsing.
