Major Police Operation on the Mongrel Mob

Seven patched Mongrel Mob members and 15 others have been arrested today after an eight-month police operation targeting the gang's drug activity.
This morning police executed simultaneous search warrants on the addresses of Mongrel Mob members in Blenheim, Picton, Nelson, Hokitika, Christchurch, Lower Hutt, Auckland, Havelock North and Palmerston North.
The warrants covered six police districts and involved about 100 police and drugs dogs, police said.
The operation focused primarily on alleged serious drug offending by Mongrel Mob members across Marlborough.

I say "At a Nelson address, a large quantity of plastic bags with Mongrel Mob insignia printed on them, that police said were commonly used for the distribution of methamphetamine, were recovered."is an absolute stupid move it would have indicated to the police it was them commiting the crimes, not a clever way to keep it discreet
