Mr Blake denied killing the 24 year old.The unnamed colleague, who was at the scene immediately after the shots were fired, said: "At no point was there any evidence that Martyn Blake had done anything wrong or at least deviated from his training or indeed the law."Mr Kaba’s family have said they are "devastated" by the outcome. "The acquittal of Martyn Blake isn't just a failure for our family but for all those affected by police violence," his cousin said. "Despite the verdict, we won't be silenced."Listen to the Today programme on Radio 4 and BBC Sounds: 6-9am Monday-Friday, and 7-9am on Saturdays.
