The newly reconstituted policing board has held its first public meeting.
The policing board is made up of nine independents and 10 politicians
It was the first time that Sinn Fein has taken part in a public session of the board.
Members of the board sat at the table and posed for cameras last week - but there were no PSNI officers present and the talking was behind closed doors.
On Wednesday, board members sat across the table from Chief Constable Sir Hugh Orde and his senior officers in public session for the first time.
Questions have been tabled on a wide range of issues.
Sinn Fein has three members on the policing board
They include Sir John Steven's investigation into allegations of collusion between the security forces and loyalist paramilitaries, and the murder of Robert McCartney, who was stabbed to death by members of the IRA outside a Belfast bar more than two years ago.
Sinn Fein voted in January to back police in Northern Ireland for the first time.
Its three representatives on the board are Alex Maskey, Martina Anderson and Daithi McKay.
The DUP is the largest political party on the board, with four members. The Ulster Unionists have two, and the SDLP has one.
The board also has nine independents.
