I think a far more equitable solution would be for conscientious Christians to hunt down the jihadists who did this and kill them. Bringing them to justice for their actions will secure the safety of innocents in the future. By this principle Christians are justified to kill. In fact, it's one of the basic tenents of Western law and one which Christians ceded to the (Roman) government 1,700 years ago. It now appears that several Western governments are shirking their obligation to protect Christians. It's foolish, because that is the foundation of their legal systems, their government -and their authority.
