The IRA almost always phoned in advance notice of bombs in civilian areas, at least that I remember. Unless they were targeting a specific person, or the British military. But when they did things like plant bombs in Manchester to blow up shopping districts, they phoned in warnings first.
Muslims, obviously, don’t bother. I guess they don’t feel their point is made without a lot of dead civilian infidels.

The IRA trained alongside muslims, and they also shared their expertise with ME terrorists. There’s not really a dime’s worth of difference between them if you are the target.
