Families and campaigners affected by state violence have no confidence in British government-controlled schemes to deal with past killings, a major conference has been told.
A steering group will also be established by victims' relatives to examine truth mechanisms relating to collusion and state-sponsored killing in the North.
The decision was taken by over 250 delegates who attended an all-day conference in Belfast on Saturday.
'State Violence State the Truth' was jointly organised by the anti-collusion group An Fhirinne and Relatives for Justice.
Among the issues discussed were the lack of truth in the inquest system, the role of media, the British government's new inquiries legislation, the policy of state collusion and the Northern Ireland Office's funding of a new internal PSNI branch to examine pre-1998 killings.
Veteran campaigner Clara Reilly told the gathering that victims of state violence cannot have any confidence in the new NIO/PSNI crime review branch.
"It is lawyers for Hugh Orde who are citing the possible use of Public Interest Immunity Certificates at inquests.
"It is the RUC/PSNI who run agents involved in murder," Ms Reilly said.
"The Serious Crime Review Team is no different a strategy than that which exists in the form of the Inquiries Act preventing the truth surrounding the killing of Pat Finucane from coming to light.
"There are equally dangers that the same people involved will use the SCRT and continue to police politically some of the personnel involved in the raid on Sinn Féin's offices at Stormont are involved in the SCRT.
"State killings constitute proportionally the largest number of unsolved killings in comparison with any other participant group to the conflict whereby the state used its sovereignty as a shield to deny truth and justice and provide impunity.
"If Hugh Orde or the British government genuinely wanted to address issues of the past then as a matter of building trust we call on them to now make fully public the Stalker/Sampson and Stevens Reports.
"Any process that examines the past must be independent, transparent, accountable, and have public confidence and support.
"The PSNI's SCRT does not constitute that criterion and is unacceptable to hundreds of families affected by state and state-sponsored violence.
"We have no confidence that it will deliver instead we believe that it will act against our interests whilst promoting state interests," Ms Reilly said.
In a poignant and powerful contribution, relatives of plastic bullet victims declared that they would never give "consent to any police force that uses plastic bullets".
On behalf of the United Campaign Against Plastic Bullets, Frances Meehan, sister of Michael Donnelly, and Helen Whitters, mother of Paul Whitters, said, "We would like to place on record today that no police force using these weapons will gain our consent.
"No body which oversees their purchase will be trusted.
"No person who has human rights or civil liberties at their hearts can credibly sit on these bodies," the statement said.
The relatives called for any future negotiations on policing issues to "ensure that these weapons of mass injury and death are removed from our streets forever".
"The introduction of the Attenuating Energy Projectile or new plastic bullet by the PSNI on April 7 is a disgraceful development.
"The introduction of yet another form of plastic bullet is another example of the lack of will of the British government to implement entirely and properly the Patten Report into policing.
"Last year we lost one of our esteemed members, Dominic Marron. He died as a result of the injuries he sustained as a 14 year-old when he was shot in the head by a plastic bullet fired by the RUC.
"He is the eighteenth person to die from a plastic bullet wound," the statement said.
Sinn Féin president Gerry Adams, who attended the conference, said that he "took great heart" from the event.
"I was very moved, as I have to say I always am, at the resilience of the people there and their determination," Mr Adams said.
"I think that, as we have seen in other cases, like the Bloody Sunday case, it's the families who have consistently driven the search for truth."
A letter from American Congressman Chris Smith supporting the need for open, transparent and accountable government institutions was also read to the conference delegates.
Referring to the six cases reviewed over recent years by Canadian judge Peter Cory as "emblematic of the problem of state-sponsored collusion", Congressman Smith specifically urged the British government to establish a "Cory-compliant public inquiry into the murder of human rights lawyer Patrick Finucane".
