Nothing sadistic. Just practical. I once had a problem with intruders on my quasi ranch. Buggers could cut through the barbed wire fence to graze their zebus on my grass and shrubs. Ended up destroying some nice trees I had planted. Simply bribed the local assistant chief and his minions to call a public baraza where I announced that I will be spreading some deadly chemicals on the grass and weeds in readiness for some upcoming project. Followed up with a notice in English and kiswahili on the main gate to that effect. Well it has been three years since I saw miscreants in my compound.
