The "Mexican cartels, including the powerful Sinaloa and the brutal Los Zetas, have infiltrated almost every corner of Oregon," and "perhaps most unnerving, cartel-connected traffickers lash out in violence to control territory, settle debts or warn rivals" as reported by Les Zaitz for The Oregonian:
Police suspect a cartel is behind the roadside execution early last year of a trafficker near Salem. They think cartel operatives shot two California drug dealers whose bodies were found buried in the sage northeast of Klamath Falls last fall. They also believe a cartel ordered a 2007 hit in which a trafficker and four friends were lined up on the floor of a Vancouver rental home and shot in the head.
The Mexican cartels move $50 billion in bulk product and bundled cash across the border each year, and have established supply lines, distribution networks and operational cells in hundreds of communties throughout the United States.
Although the Obama Administration insists that there is no spillover violence from drug cartels the dead bodies on the north side of the border stubbornly belie the President's absurd claim.
