What sort of homage is it to the King of the Beasts when you “protect” it like some helpless target?
No self-respecting T-Rex is going to need a puny fence, warning sign, alarm and video camera system to protect it. Fifty or so flesh-rending teeth are all the protection it needs, thank you very much!
Of course, teeth won’t protect you from asteroids, but then again, neither will CCTV.
