Well, it's been a few days since the terrorist attacks in Paris. The dust has mostly settled and speculation has tapered off. We're pretty sure what we know or suspect is, in fact, true: ISIS has claimed responsibility and there is little reason to doubt their veracity, in this case at any rate.
The French — indeed, all of Western Europe — are shocked — shocked, I tell you — that terrorists can so easily obtain better, more deadly, weapons than the Paris gendarmerie typically tote. The ordinary Jacques-sur-la-Rue, I might add, is a criminal for carrying almost anything that might be called 'a weapon'.
I could rant on and on for paragraphs about how important it is for ordinary people to be able to be their own first responders and how that requires that they be able to act — forcefully — in their own defense. You've just heard all the ranting I'm going to do, except...
I do wish to point out something L. Neil Smith has already expounded: 'terrorism' is a diffuse problem and it will not succumb to a targeted solution; only a diffuse solution will fit a diffuse problem. What this means, on net, is that we cannot expect the police, the FBI (or, in France, DCPJ), or the NSA to always be on top of the situation. Yes, they will thwart the occasional plot, but not every one. The only thing that will put a bullet into the nefarious plans of terrorists is the thought that Jacques Bonhomme will put a bullet into one or more terrorists.
I am pretty sure France will not take my advice. Too bad, but I've done my part.
