Yes, but it you just say it's an individual action, that's ok on one level, of course it's an individual but in an increasingly unequal country and world, violence and terrorism aren't going away.
Considering whatever community you like to focus on, people feel afraid, aren't getting their needs met and some of those people won't just accept or might not be able to and one day they break. There's none so blind as those who can't, or don't want, to see.
It's a shame that the fact that it's Northern Ireland which I saw labelled as England's first colony only the other day, will encourage people to ignore the poverty and misery in which so many live.
