A new Gardai Inspectorate report has made the recommendations.
A former detective believes giving officers power to sanction illegal conduct from informants will lead to complications between the Director of Public Prosecutions, and the Gardaí.
It follows a new report by the Gardaí's Inspectorate which proposes informants from criminal gangs providing intelligence to officers can commit offences in certain circumstances.
It also suggests sting operations could be carried out to catch corrupt politicians and officials.
Mullingar's Pat Marry-a former private detective and Senior Investigating Officer with the Gardai says a duty of care must be upheld:
