I wonder about the deterring effect. How many attacks do not occur because security is there. It's hard to measure, with a high risk to reward factor.

Yea, that's what I tell people when they tell me this rock hasn't been protecting me from tiger attacks. Maybe the rock isn't doing anything, but is the risk of being mauled by a tiger worth testing this? Use your head people!
