Combating organised crime and drug-trafficking, which is dominated by large, international criminal organisations, will remain the main security challenge throughout the region, buoyed by increased funding from the US under the Caribbean Basin Security Initiative (CBSI). The proliferation of lower-level domestic gang activity will continue to boost the region's murder rates, which are already extremely high on a per-head basis. Although many governments will continue to develop new initiatives to combat crime, corruption of public officials and the undermining of laws and institutions will hinder their effectiveness. Drug seizures and arrests in Jamaica since the 2004 launch of Operation Kingfish, an anti-crime initiative with international support, have led to some displacement of trafficking to the eastern Caribbean, Central America and Mexico, as drug shipments are rerouted. There are concerns over an increased flow through Venezuela, which in recent years has become a major drug conduit, to Guyana, Suriname and the eastern Caribbean. New coastguard vessels and coastal radar systems acquired by Trinidad and Tobago and Barbados could begin to show results in control of the eastern Caribbean drug routes in the outlook period.
