If this had happened in America, at a lefty mag/paper, they wouldn’t have been armed either.
That is a very good point. I was thinking that if this had happened in the US, at a workplace that had received as many death threats as Charlie Hebdo, more than one permit holder would have gone to the trouble to be armed. I wasn’t factoring in how far left CH is. Yes, that would certainly impact the # of firearms present, and I agree with your estimate...zero.
