The video (warning: contains graphic images of lethal violence), caught randomly on a warehouse security camera, is chilling.

Five young men walk down a quiet street in Tegucigalpa, Honduras. A big black SUV pulls up, followed by a second vehicle. Two masked men with bullet-proof vests jump out of the lead car, with AK-47s raised. The two youths closest to the vehicles see that they have no chance of running, so they freeze and put their hands in the air. The other three break into a sprint, with bullets chasing after them from the assassins' guns. Miraculously, they escape, with one injured – but the two who surrendered are forced to lie face down on the ground. The two students, who were brothers 18- and 20-years-old, are murdered with a burst of bullets, in full view of the camera. Less than 40 seconds after their arrival, the assassins are driving away, never to be found.

The high level of professional training and modus operandi of the assassins have led many observers to conclude that this was a government operation. The video was posted by the newspaper El Heraldo last month; the murder took place in November of last year. There have been no arrests.

Now, the Obama administration is coming under fire for its role in arming and funding murderous Honduran police, in violation of US law. Under the Leahy Law, named after Vermont Senator Patrick Leahy, the US government is not allowed to fund foreign military units who have commit gross human rights violations with impunity. The director general of Honduras' national police force, Juan Carlos Bonilla, has been investigated in connection with death squad killings; and members of the US Congress have been complaining about it since Bonilla was appointed last May. Thanks to some excellent investigative reporting by the Associated Press in the last couple of weeks – showing that all police units are, in fact, under Bonilla's command – it has become clear that the US is illegally funding the Honduran police.

So, now we'll see if "rule of law" or "separation of powers" means very much in a country that likes to lecture "less developed" nations about these principles.

Why would the Obama administration so stubbornly support a death squad government in Honduras, going so far as to deceive and defy Congress? To answer that, we have to look at how the current government of Honduras came to power, and how violent repression of any opposition plays a big role in keeping it there.

The government of Honduran President Pepe Lobo was "elected" after a military coup overthrew the democratically elected government of President Mel Zelaya in June of 2009. Zelaya later told the press that Washington was involved in the coup; this is very believable, given the circumstantial evidence. But what we know for sure is that the Obama administration was heavily involved in helping the new regime survive and legitimize itself. Washington supported Lobo's election in 2009, against the opposition of almost the entire hemisphere. The Organization of American States and the European Union refused to send observers to an election that most of the world viewed as obviously illegitimate.

The coup unleashed a wave of violence against political dissent that continues to this day. Even Honduras' Truth and Reconciliation Commission – established by the coup government itself – found that it had "undertaken political persecution … and that it was responsible for a number of killings committed by state agents and those acting at their behest, in addition to the widespread and violent repression of rights to speech, assembly, association."

This was noted by the Center for Constitutional Rights, in New York, and the International Federation for Human Rights, in Paris, in a report (pdf) submitted to the International Criminal Court. The CCR/FIDH report also identifies "over 100 killings, most of which are selective, or targeted killings, occurring even after two truth commissions concluded their investigations". Their report goes through October 2012:

"The killings are one horrific manifestation of the broader attack which is also characterized by death threats against activists, lawyers, journalists, trade unionists, and campesinos, as well as attempted killings, torture, sexual violence, arbitrary arrests and detentions. The True Commission [the second, independent Truth Commission] described the regime's "attack" as one of using terror as a means of social control."

Which brings us the elections scheduled for later this year. Once again, a social-democratic party is in the race, including people who courageously defended democracy against 2009's military coup. Its presidential candidate is Xiomara Castro de Zelaya, the wife of the president whom Washington worked so hard to get rid of. This party is among the victims of the government's political repression: in November, LIBRE mayoral candidate Edgardo Adalid Motiño was gunned down after attending a rally for Xiomara Zelaya.

So there you have it. A death squad government may not be the Obama administration's first choice, but it prefers it to a leftist government that Hondurans might elect if they were to have a free election. The current government belongs to Washington, just like the US military base that the Pentagon would like to keep in Honduras indefinitely.

If all that sounds disgusting, and reminiscent of President Reagan's death squad governments in Central America, it's because it is both. The question right now, as in the 1980s, is what will members of Congress in Washington do about it?
