Lebanon’s judicial investigation of the Beirut port explosion started with political wrangling over the naming of a lead investigator, military threats to jail leakers and doubts over whether a panel appointed along sectarian lines could be fully impartial. So for many Lebanese, their greatest hope for credible answers about the blast that wrecked much of their capital may lie with outsiders: the French forensic police who have joined the probe and FBI investigators are expected to take part. French teams have pressed ahead at their work, sending divers into the underwater crater, taking explosives samples and preparing recommendations for both French and Lebanese magistrates. Among the French judicial police on the case are men and women who responded after the 2004 tsunami in Japan, the 2010 earthquake in Haiti, and the November 2015 and Bastille Day 2016 terror attacks in France, The Associated Press (AP) reported. The Beirut explosion lies at the crossroads of a disastrous accident and a crime scene. It still was not known what sparked the fire that ignited nearly 3,000 tons of ammonium nitrate that were stored for years in Beirut’s port next to densely populated residential areas. Documents have emerged that show the country’s top leadership and security officials were aware of the stockpile. Search and rescue crews flew in from around the world in the immediate aftermath and found themselves looking at a scene that was both familiar and yet strangely alien. “In an earthquake, it’s easier because we can understand ... how it moves. But in this case, we didn’t have enough elements to understand what happened,” said Alberto Boanini, a member of the Italian rescue team. The team has seen its share of quakes and forest fires, but nothing quite like the port in Beirut, where he said it was hard to fathom what could level it so completely. Many Lebanese want the probe taken out of the hands of their own government, having learned from past experience that the long-entrenched political factions, notorious for corruption, won’t allow any results damaging to their leadership to come to light. The explosion killed more than 175 people, injured at least 6,000, and left tens of thousands homeless. French officials say they have the access they need but will not say whether their inquiry can extend to questioning witnesses or requesting documents. They hand over their findings to the Lebanese, but keep a mirror copy for a French inquiry. The FBI is also joining at Lebanese authorities’ invitation. Top Lebanese officials, including President Michel Aoun, have rejected calls for an independent probe, describing it as “a waste of time” and suggesting it would be politicized. In its last decision before resigning under pressure, six days after the explosion, Prime Minister Hassan Diab’s government referred the port explosion case to the Higher Judicial Council, Lebanon’s highest justice authority, to carry out the investigation. An argument then ensued with the outgoing justice minister over the investigation’s lead judge. The outgoing minister proposed a figure whom the panel rejected as too close to Aoun’s party. After wrangling back and forth, they settled on a compromise, Judge Fadi Sawwan, a former military investigating judge. The authorities have so far arrested at least 19 people in connection to the blast, including the head of the Customs Department and his predecessor, as well as the head of the port. Lebanese say they want to see top officials who knew about the existence of the ammonium nitrate being investigated. “They will blame the small guys while the ones who are really responsible will get away with their crime, that’s what will happen,” said Jad, a 38-year-old computer engineer who declined to give his full name in line with his company’s regulations not to discuss politics. “Look, it’s simple. If this time there is no credible, serious investigation that will lead to the punishment of everyone responsible for this disaster, it is goodbye Lebanon. No one will ever want to live in this country again,” he said, standing on a bridge overlooking the decimated port. According to AP, explosions have marked a grim timeline in Lebanon’s modern history and have killed presidents, prime ministers and countless journalists and activists during the country’s 1975-90 civil war and beyond. Almost none of the perpetrators were ever arrested or tried, and the truth was invariably buried. Lebanese had high hopes that the UN-backed tribunal investigating the 2005 killing of Prime Minister Rafik Hariri would be a chance to end impunity in Lebanon. But it took 15 years and was marred by doubts, politics and more deaths. The tribunal is to issue verdicts Tuesday.
