article: It raises questions about the conduct of one of the UK's second biggest firearms unit at a time when Manchester has recently been hit by a terror attack. A public inquiry into one of the deaths has heard about flawed intelligence, a senior officer destroying notes and employment of an officer disciplined for assault. Its former head of training, John Foxcroft, said he left the firearms unit due to its "aggressive" tactics. Many of the officers in the cases are still serving. Greater Manchester Police (GMP) said its firearms officers "volunteer for the role and do a very difficult job, quite rightly under the highest levels of scrutiny". Here is the story of the three fatal incidents, with new findings uncovered by the Victoria Derbyshire programme's investigation. "He was a beautiful person inside and out," Anthony Grainger's partner Gail says. The couple lived together with their two young children. "I remember thinking, 'My life's perfect.' Then he nipped out - and he didn't come home." Anthony Grainger was unarmed in a car when he was shot by police in Cheshire, in March 2012. Police intelligence had suggested he was going to carry out an armed robbery with two associates, also in the car. Mr Grainger had previously been found guilty of handling stolen cars, but had no convictions for violence. The two other men did have convictions for violence. Police saw one as very dangerous. Mr Grainger was killed in a car park on a busy Saturday evening in the village of Culcheth. Armed officers said they saw him drop his hands in a move interpreted as him going to grab a gun - he was shot once, fatally. But another man in the car, David Totton, told the inquiry no warning was given before the shot was fired. All three men in the car were unarmed. On the day of the operation, the firearms team had been on duty for 14 hours when it was told to move in. There were 16 firearms officers. Several had failed training courses and it was argued during the public inquiry they should not have been on the operation, which Greater Manchester Police disputed. One officer, known as X7 - who had directed the operation on the ground - had failed a firearms course with the Met Police, who removed him early as his performance was "adversely affecting other students." Another, known as Z15, had failed a safety course shortly before the operation after three extreme safety breaches in potentially life-threatening situations. A firearms expert told the inquiry these were so "fundamental and inherently dangerous" that it should have led to Z15's "immediate suspension". Martin Harding, a former superintendent and firearms officer with Greater Manchester Police, told the BBC: "A force such as Manchester has got resilience, so there shouldn't be a reason why you would have someone on a job who wasn't trained to carry out their role." It emerged during the public inquiry that the officer who fired the gun - referred to as Q9 - had seriously injured a suspect during a
