As many will remember, Damian Pachter is a former reporter with the Buenos Aires Herald who fled Argentina following his Tweet confirming the death of Alberto Nisman. He is the same man whose flight details to Israel were made publicly available by the Casa Rosada Twitter account in a flagrantly irresponsible act. During a five hour hearing in Tel Aviv with Prosecutor Eduardo Taiano, he handed over documents but is still refusing to reveal the source which led to his initial Tweet over Nisman's death.
His life may very well still be in danger, so this comes as no surprise.
