In this RNZ article, Andrew Little makes a distinction between (mainly) adolescent 'big-noting' and genuine terrorist rants:
"There are a lot of people who say things on social media that are kind of big-noting. They can be vile, they can be offensive but there's no either means or intention to carry through the comments that are made through expressions of violence.
"On the other hand, there are people who make violent threats towards classes of people, groups of people, types of people.
"The role of the agencies, among other things, is to do their best to distinguish between what is a real threat and what is just big-noting on social media."
I think this attitude is mistaken and is part of the problem. Any comments of this nature, whether they can be acted on or not, need to be immediately and forcefully squashed, as happened recently in Australia. Big-noting is a step on the path to eventual violence. There can be no tolerance for it. That is why we have reached this point now. Little needs to wake up and get serious.
