I can see both sides to some extent............. the police deliberately running towards a bomb,takes guts,and possibly has something to do with the eight shots,unlike our american cousins my exposure to firearms was limited to my time in the services,and it has been suggested that the small calibre weapons they were using neccesitated that number of shots I wouldnt know.
Against that the family are saying his visa was fine and that he didnt vault the turnstile,and was wearing a denim jacket.
In the end the poor guys remains dead whtever the rights and wrongs.
