The officer thwarted the group’s plan after he was alerted by a concerned citizen about the bus loaded with Haitian children.

I do not know if this is the same officer mentioned in the article above or not, but if it is, that’s interesting in and of itself. It leads to an important question:

Did he become a witness to avoid any culpability on his own part in trying to help the 10 get the kids out of the country?

Ten Americans accused of trying illegally to take 33 children from Haiti had met with a Haitian police officer and a Dominican official the week before being stopped at the border, interpreters who worked with the group said Wednesday.

One interpreter said the officer offered to help the Americans with the paperwork required take the children out of the country.

Around noon Wednesday, Haitian authorities took away for questioning a Haitian police officer who works at the Dominican Embassy, officials said.

They said he would be asked whether he provided illegal paperwork to the Americans to facilitate their efforts to remove the children from the country.
Three interpreters who had translated for the Americans told CNN that the Americans met last week at least twice with the officer — at the embassy and consulate.

One interpreter said representatives of the group met with a Haitian police officer on January 26. The officer told Silsby that her group couldn’t gather Haitian children as they were doing, but then offered his help, the interpreter said.

“They met a police guy and he told them that he could help, and he was helping them with some paper,” interpreter Steve Adrien said. “We did not meet him in a police station, but in the street in a car.”

The Americans met again with the man in Port-au-Prince on Thursday, near the Dominican Embassy, the translator said.

“He was helping Laura [Silsby] to get in touch with the ambassador in the Dominican Embassy,” said Isaac Adrien, Steve’s brother and another of the interpreters.

He said the group came away from the meeting with a document from the embassy that the Americans took with them to the border Friday.
