I was playing on Wall Street and was sniped on two occasions by one guy when he didn't have sight of me. Both occasions he sniped me through a tree which I could see on my killcam. Now, I like to visor tag enemies and know that when you do the outline of your victim can be seen through obstacles.

My question is does this show up on the killcam? I know the red name and icon does but I'm not sure if the outline does.

No I don't think so. If you get killed if you're tagged, it's not possible to see if you were. My friend tagged me when I was on the other team and I didn't see the red tag in the killcam.
