Within Samoa, reports of organized gang members growing and selling cannabis have become common. In the early hours of Monday 7 May 2012, Samoan police officers received gunshot wounds during a police raid in Faleatiu village near Apia. Sources said that there was a shoot-out between police and people involved living on this particular land when the drug raid took place. Faleatiu village has been the target of police investigations as one of the main sources of cannabis.
In recent years, reports of organized crime occurring in parts of Samoa were noted. The growing of cannabis and selling it. The import of weapons into Samoa from neighbouring countries including the United States have raised alarming concern over the possibility of increased gun crime in Samoa and the possible import of these weapons to New Zealand, which was described in a New Zealands Journalist report as a 'warzone' if this were to be.
Australia will build a new police headquarters in the Samoan capital Apia, as part of a major initiative to strengthen the Samoa Police Service. The Samoa Australia Police Partnership operates within the framework of the Samoa Australia Partnership for Development and is founded upon and institutional relationship between the Samoa Police service and the Australia Federal Police (AFP) within the broader context of external support to Samoa’s law and justice sector. The Samoa Australia Police Partnership is a component of the Pacific Police Development Program, which is a Government of Australia initiative supporting a broad range of bilateral and multi country police capacity development initiatives throughout the Pacific region.
The Samoa Australia Police Partnership commenced in January 2009, prior to which AusAID provided support for police capacity development under the Samoa Police Project (SPP) (2004–2008). While it is widely recognized that noticeable improvements in SPS performance were achieved during the life of the SPP, it is also acknowledge that ongoing assistance to the SPS is required. With a new Commissioner having been appointed in September 2009, and a new senior executive, it is an opportune time for the AFP to forge a new program of assistance to the SPS.
