Update on the camera kill rules

The camera kill, or "I take a picture of you instead of using a scope'd rifle" rules are as follows:

There can only be one person in the shot. (Should cropping be legal, guys? As long as the other parameters are met, I mean)
You must have the entire torso or the whole head of the target in the shot as well.
I had better be able to recognize the guy.

There must be an indicator of time in the shot as well. This means a clock, a calender, a newspaper stand, etc. This isn't just about verifying time of death (making sure you didn't kill the guy during a no kill period or whatever, we're on the honor system here) it's about making a tremendously powerful attack more reasonable. I could have said "A cat must be in the picture" but indicators of time make more sense. Note: The watch the dude may be wearing does not count.

"How the hell am I going to pull that off?" you say. Well you could wait for them to stand near one of these objects, or you could go and attach a clock to their car or outside of their house, something ridiculous like that.
