They said there was no physical evidence to support the allegations.The prosecution said Gallagher’s own text messages and photos incriminated him. They included photos of Gallagher holding the dead militant up by the hair and clutching a knife in his other hand.A text message Gallagher sent while deployed said: “Got him with my hunting knife.”The panel of five US marines and two sailors, including one Seal, listened earlier on Tuesday to a recording of Lt Thomas MacNeil, the first witness in the court martial of Gallagher.MacNeil described hearing Gallagher say “he’s mine” on the platoon radio after learning there was a prisoner who had been wounded in an airstrike.MacNeil testified about seeing the prisoner alive and then returning later when he was dead.MacNeil also testified about a custom knife that Gallagher always carried or would hang on the wall of the room they shared. The defendant was accused of using a knife to stab the wounded militant in the neck. He was also accused of shooting civilians, in separate incidents in 2017.Gallagher had pleaded not guilty to seven charges, including the violations for posing with a human casualty and for allegedly retaliating against Seals who reported him.In March, 18 congressional Republicans wrote to the navy secretary, Richard Spencer, raising concerns about Gallagher’s confinement at a navy brig in San Diego.They said family and friends reported Gallagher had not had sufficient access to his attorneys and was not receiving enough food or adequate medical care, describing him as “a decorated war fighter”.Trump then weighed in from his Florida resort at Mar-a-Lago. Before leaving to play golf one morning he said in a tweet that Gallagher would be moved to less restrictive confinement.This was “in honor of his past service to our country”, Trump wrote, adding: “Process should move quickly!”
