Spraypaint cameras

Letting intruders have spray paint would be kinda cool. They could use it to mark each other (spraying different colors on one another so they can identify each other from far away), they could use it to blind security cameras, or use it to draft out a plan. 

Also, I had another idea, and honestly, it seems like a pointless idea, but for some reason, I just thought,
"wouldn't it be interesting if there was a mode for the binoculars to print the photos to a piece of paper, and place them on walls." (the same way you put things like wall tags on walls)

Again, it's a pointless idea and probably a waste of time.
