Come on now, you dont want to kill the guy. Maybe one of them foot traps so hes hanging by one leg upside down 10 feet up?
Dont forget, idk your regs, but in NY the trappers hand book says all sets must be checked every 24 hours!
In all seriousness, dont do anything stupid. If this guy is really just confused, then he dont deserve to meet his maker. Catch him, but give him the benefit of the doubt and let him try to explain him self. If that dont work then...
