This includes the thousands of people who are beheaded each year by the Mexican/Colombian cartels, which, if you look at it this way, can be blamed on the US government's 'criminalization of victimless drug use'. The US government's policy might be stupid - but the cartels are also evil, and we should do as much as possible to try to curb these kinds of atrocities.
Look the drug war is terrible, drugs should de-criminalized and treated like a health problem as they are in Europe. However, you can recognize this while recognizing that the people who traffic drugs tend to be engaged in some pretty reprehensible behavior, and money laundering is one of those things (along with human trafficking and gang violence.)
