If the interview with Measho Tesfamariam hasn’t happened yet, I would humbly offer a couple of suggestions to the interviewer. Eyewitness testimony is notoriously unreliable and inaccurate, but if approached correctly, it can still be useful. Elizabeth Loftus showed that something as simple as the words you use to question an eyewitness can influence their answers. https://webfiles.uci.edu/eloftus/LoftusPalmer74.pdf Also, we already know Measho is a self-serving liar — lying about his age when he arrived in Europe, lying to the families of the missing and lying about his involvement in the operation. With that in mind, I would suggest the interviewer begin with broad, open-ended questions about Measho’s own crossing — “tell me about your crossing.” Let him fill the space with his own words, then, work to nail down dates, places and people. Using his own crossing as a memory anchor may help him remember more accurately what happened in the days, weeks or months before he crossed — and specifically what happened with the Ghost Boat. It may be hard to remember what you were doing on June 27th of last year, but if I ask you if you remember the 4th of July or some other national or religious holiday and then ask you about the days before or after, you might have an easier time. Giving Measho some memorable point to work back or forward from may help him remember better and give you better information. And, of course, be sure to ask him information you already know and can verify to determine how truthful he’s being with you. I’m very interested and excited to see what Measho has to say, assuming the Italians allow the interview to proceed. Good luck!
