You dont need booby traps for deer or rodents, just natural deterrents.
If your worried about jackers, then your spot isnt concealed enough an you need to put more time and effort into your grow spot.
As far as booby traps, as indicators wouldnt be a bad idea.
But booby traps to injure someone, not a bright idea. If I was walking through the woods on a hike, myself or my dog got injured by a booby trap, I'd stick around an gut the mother fucker.
And as far as the police go, they'd do the same thing, only with criminal charges. I'm sure they'd label it something along the lines of cultivation, and assault on a police officer in whatever degree.
