Add a Killcam?

As always there's a lot of talk of cheating. 

Now I've often been killed in ways that looked dubious to me in the moment: being in full cover with the killers silhouet showing well behind that cover. Or people sprinting into a room and instantly snapping onto me and one-shot killing me. But there's no way to really know how you were killed or exposed to them.

A killcam feature would allow us to better understand how/why we were killed. Giving us feedback on our own 'playstyle' but also stop us crying 'cheater' whenever someone legitimately kills us.
