We terrorise you, you terrorise us. Only difference is we kill you in far greater numbers than you can ever dream of.
The war on terrorism will end when a new enemy can take it's place. The smart money is on China, but don't never count the Red Menace out, good outside bet they come good at the last minute.
The discussion needs to turn to how can people defend themselves. How 10/20/30 people trapped in a theater CAN overwhelm 3 attackers. How these people will not be willing to spare you no matter how cooperative you are or how sympathetic you are.
If you can't flight, fight.
A fairly large number of people die from influenza every year, but we don't have a mass surveillance dragnet to try and isolate flu vectors, for good reason. We do, however, have a fairly robust vaccination system which is a sensible precaution to take.
That's what confuses me the most about these attacks. Many people have legitimate grievances against NATO forces, but how does that lead to shooting random Parisians? It's so wasteful and counterproductive.
But it's completely wrong to conclude that the right thing to do is therefore nothing. As we learn more about who, what, why, and how this happened the first goal is to hunt down, arrest, put on trial, and if found guilty imprison for the rest of their lives (or execute) anyone who contributed to this attack. Every angle must be criticized to understand what effective countermeasures could have been in place to detect, disrupt, or kill the attackers sooner. There should be a tremendous outpouring of support for all the people and families impacted.
The most sickening is the celebratory response from various camps, and I wonder if that's happening anywhere inside France.
Particularly if this turns out to be a home brew attack, the Islamic communities bear a tremendous responsibility, not for the attack, but going forward, in significantly strengthening and mobilizing all their resources towards preaching nonviolent protest and leading the efforts to root out radicalized groups in the community. Where are the Islamic MLKs to rally the community against radicalization? The fear-and hate-fueled backlash against French Muslims may only be stemmed by a disproportionate response against the violence from within the communities.
And just a pedantic point, we actually do spend a reasonable sum on detecting flu trends by "surveillance" of hospital visits and even monitoring Google searches to identify and better respond to possible outbreaks.
