Actually I missed a bit of his quote out, it was 'Kill or be killed, shoot first ask questions later'.
He said that many times he had been sitting on his tractor or out in his fields, heard a rustling in the bushes and shot first. He would then send a worker to investigate and quite a few times he had shot somebody. Although he was saddened by it he said that he had no option, that's how it worked, nobody should be sneaking around his property.
I asked him what if it was one of his workers who had 'strayed' for some reason and he said they knew the rules and they would shout me to tell me what they were up to etc.
We didn't have it that bad in Nigeria and I never heard of ex pats killing Nigerian trespassers but we knew it was still shaky ground if they had got into the house. These Teef Men are not interested in TVs or gizmo's but know that the owners know where the proper valuables and money is.
Probably none of you here have any experience of being flagged down every single night by the Police or Army and having a rifle shoved in your head just because they want 'dash' (a bribe). We never kept money on our persons but always made sure we had sandwiches, crisps and chocolate in the car every night.
