It perturbs the secular mind to have a ideology (besides their own) that can justify violence. Their view of “religion” is that is ought remain passive and open to the advances of secular influence. As in, “religion is a private matter,” a “matter of faith and conscience.” Unless a Christian conscience opposes something like homosexuality or abortion and then the Christian is told “not to impose” their “religious” beliefs on others. So much for toleration — it has always been a one way street.
But the subject is violence. When might a Christian kill?
Of course a man ought resort to violence in order to defend his wife and children (and himself) from death or severe bodily harm. Those men who have abnegated this role to the police are very trusting — sometimes it works out. But mostly the murders take the initiative and by the time the police are called the crime is done, a child or wife destroyed, and an “investigation” may be started. Once in while they actually catch a criminal, assuming he is fairly low on the social pecking order.
Who is not low on the social order? Armies, police, cartels, gangs, and hired guns. These folks almost never see judicial repercussions for killing — it is a “protected” sort of killing for police and the military. And an unacknowledged practice for other professional practitioners of violence. It could “businessmen” who compete by killing those who get in their way. And woe to a policeman who dares challenge their power.
In Mexico most killings are not even investigated. Do you think communities there have an interest in protecting themselves? In one town the police were disbanded because they all worked for the Cartel. So calling 911 is never and option for them. Imagine that poor trusting Mormon family that was slaughtered. No one was going to come to their aid. They trusted and died.
