“He was one of my soldiers, an excellent officer. Even if he knowingly acted to cause grave harm to national security – which we stopped at the last minute – he should not have died in a military prison,” Chief of Staff Lt. Gen. Aviv Kochavi said on Wednesday. The circumstances of his death will be thoroughly investigated. The general went on to say: “He knew what he was doing, and I don’t know why he did it. He was a first-rate officer.” Gen. Kochavi added that the veil of secrecy clamped down on the episode was partly to protect the suspected officer and his family. He was behind bars from last September until his death in a military prison last month pending trial.
