I live in the UK and very few people have guns, even the police are not routinely armed. Yet, we still have these kind of events from time to time.

You could ban guns today and they will still be around for the next few hundred years. It's natural to search for answers in times like these but sometimes there just aren't any.

Realistically: no, we don't. The one and only school shooting, Dunblane, was a catalyst for the UK gun ban, and that was in the 1990s. There have been a few terrorist attacks carried out with bathtub-made explosives, some truck and knife terrorism, and a few shootings a year carried out mostly by organised crime.

The US shooting epidemic is far more deadly than the Troubles was, an actual paramilitary civil war.

The US has spent far more effort trying to ban abortion than to deal with school shootings.
