Fighter pilots have had gun cameras for ages, presumably for debriefing purposes and counting kills. Now it seems that this habit is moving down to infantry level but for other reasons.
The proliferation of DVR cameras in battle ground and the access anyone have for phone cameras made the result of the conflict more of a director cut then a casualty count.
The Muhammad Al Durrah incident in which a Palestinian kid was supposedly killed by Israeli forces according to a French media changed all that. Now evidence collection is part of the special ops routine – Mitigation of ex post legal assault. Now the French again are issuing DVRs for police officers.
The real challenge is managing all that Big data that is gathered and using it smartly for defense against the hostile usage. I guess it calls for some ability for E-discovery as well as automatic censorship.
