Five Humberside officers - Constables Nigel Thomas Dawson, 39, Neil Blakey, 42, Mark Ellerington, 36, and Matthew Barr, 38, and custody Sergeant JohnDunn, 40 - deny the manslaughter of Mr Alder.
Speaking after Grenfell was jailed for murder, West of Scotland procurator fiscal JohnDunn said the case involved the tragic and "needless loss of life of a man who was simply trying to protect his property".
