I can't say I'm surprised.

Reports I've heard out of France put the toll at between 120-160 dead; some reports say the perps are also dead, others aren't sure.

I am...unsurprised, to say the least.  I am also, to some extent, unsympathetic.

The people of France, like us, choose their "rulers" in elections.  Their "ruling class" chose to permit the waves of invaders inside their borders, apparently without even bothering to check baggage.  That, in turn, both permitted and damn near encouraged the recent events.

I cannot feel sorry for people who invited in and welcomed those who seek wage war, with or without a nation* backing them up.

Does that mean that I'm going to be unsympathetic to our own people if it happens here?

In a word?  Yes.

To an extent.  However, I don't think they'll find Americans as easy of targets, unless they deliberately hit gun-free zones (which they likely would).  However, after what's happened in Paris, I strongly doubt otherwise law-abiding carriers will leave their means of self-defense behind.

Other than that...again, the American people have permitted gleefully placed in charge those who would welcome in our enemies with open arms (and perhaps the hope that those enemies will take out a few of those who vote against the socialist/fascist/progressive agenda, and remove enough "no" votes to change the political landscape).

So, yeah.  I'm not feeling a whole lot of sympathy.

I am not Charlie Hedbo.  I am not a Parisian.  I am not a victim.

And I don't feel too sorry for those who choose to be a victim in some weird version of Sister Bertha virtue signalling.
