Re-assessing policing policies in co-operation with the Garda national drugs unit is a proven method of supply reduction and there is a need to promote fresh approaches. Policies such as Operation Dóchas, Operation Cleanstreet, Operation Mainstreet and Operation Nightcap are aimed at preventing the supply of drugs in nightclubs and suspected trouble areas through undercover and surveillance works. Where positive results can be measured from policies, resources will be allocated to expand mainstream approaches.
