Yes, I have. And there are better ways of doing it.

You could, in example, show a directional cone of where the shot came from on death. It tells you something, but not everything.

Planetside 2, and similar, gives you literal wall hacks for 20 seconds. I play with friends often, so when one of us dies we end up describing the player’s exact movements post-death without even thinking. That’s completely broken.
