Suggestion to implement Kill Cam

Hello,
As a player who has recently started playing the game I have enjoyed it immensely and depending on how this goes I will give further suggestions in the future.

I am finding it difficult to become better at shooting, since the training at the shooting range is too easy compared to actually hitting players in-game. But I guess that will happen in due time.
What I really think would be useful or at the least very pleasant would be to add a kill cam. After spending so much time in one game looting, being careful and etc. it is a shame to just get killed really fast out of nowhere and that's it. What would really be nice is to see how the enemy killed me. I think the game would benefit a lot from a kill cam. Not only is it satisfying but that would help me learn how to shoot as well, seeing how the player who killed me did it. 
What does everyone think? I feel having such a thing would greatly increase my pleasure from playing the game.
