Depends on what you consider policing.

I do not know any of them or the conditions of when, why and how those images were taken. Nor do I know if any of the soldiers have been brought up on charges due to any action taken in any of those pictures so I cannot comment on them in respect outside of saying if those were infact malicious or negligent acts..then they are wrong. On the same note, I can not say if those acts are commonplace or if they are isolated incidents....and niether can you. :shrug:
