Officers Under Investigation

Request 1
The BBC is reporting on an alleged group of police slackers:

'There were officers sleeping on duty, there was officers bringing camp beds to work, they were bringing sleeping bags, they were setting up the briefing room to be a cinema, were going out and getting popcorn so they could all watch a movie on night shift instead of patrolling.' https://www.bbc.com/news/uk-northern-ireland-61650204

Please provide the number of officers under investigation relating to the whistle blowers' claims of slack behaviour?

Request 2
The Chief Constable has proposed changes to misconduct hearings:

'He said he has proposed reforming police misconduct hearings in Northern Ireland by replacing senior police officers with "legally-qualified chairs", who could speed up proceedings and increase public confidence in the independence of decisions.'

Please provide all information held relating to the timescale for the implementation of his proposal.
