I have to he honest here and think that, to a degree, we have brought this upon ourselves.
We've used technology to create certain types of devices and this has brought work for people and profits to be made. Which is fine.
But somehow, we've let the genie out of the bottle with the expectation that people will use these devices with good intent, and yet, here we find ourselves a day after Paris, with conversations about how said devices are being used to harm others.
Maybe, just maybe there needs to be restrictions put on the production (and/or sale) of such items which might then lead to a reduction in deaths (or injuries) to other humans? And maybe we should all be accountable for these problems, by not creating a "demand" for them in the first place?
