The central theme is that lone-wolf style IS attacks grab headlines, but that the kinds of people who conduct these attacks are usually not very numerous, competent, or threatening because of the same reasons that they tend to be attracted to IS. Part of what I’m hinting at without saying it is the lack of necessity for sweeping anti-terror legislation that is usually justified by this sort of thing.
But in essence, yes, I’m saying they could be more effective and intelligent, but that’s not the thrust of my point here. I’m saying they’re usually bad at what they do for reasons relating to their cause, and this is also part of the reason why we don’t need to implement new draconian laws on the relatively rare occasions these people do get it together to pull something off.
