The way Chinese nationals are being attacked and killed makes me think it won't be long before they stop coming to Pakistan. Today a security guard shot two of them, one of whom is in serious condition in the hospital. The problem here is that in Pakistan most security guards are from the wild north, where they are brainwashed into believing that all non-Muslims should either be converted to Islam or be killed. For this reason, I've decided never to employ a Muslim driver. The Christian driver I have nowadays has been with me for more than five years. Before that I had mostly Pathan drivers who would disappear many times with the excuse that they had gone to a distant mosque to pray. They would also go to their home towns without notice, as they wanted their wives to produce children every year, and they wanted to ensure that the children were theirs.
The provincial home minister has made the usual noises about vetting security guards before employing them. I'd advise him to ban security guards from the north entirely and employ people (whether Muslims or others) from the south. That's the only way this problem can be solved.
It's reported that the security guard opened fire after an argument with the victims. I wonder what they were arguing about. I suspect that the guard suddenly remembered his mosque imam saying that all non-Muslims should be converted or killed and he did exactly that. Maybe I'm wrong.
