If this news is true (and frankly I find it difficult to take anything in this case at face value) then how, if the police and security services were monitoring these people, could they confuse the downloading of child pornography with terrorist activity? It reinforces the complaint that they maybe had some information, didnt investigate it competently or thoroughly, jumped to conclusions and as a result someone got shot. It just makes the police or security services look even more unaware of what was really going on.
