After the Paris attacks, will gun sales go up?

[discntnt_irny_srcsm]

17. The short answer; yes

Due to the sense of the word "after" meaning in the future, yes, guns sold per unit of time (day, month, decade...) will increase. Gun and arms sales will always increase barring any partial (or total) extinctions of humans. Not because of Paris nor terrorism but because people are prone to established habits like collecting, hunting and, occasionally, killing aggressive predators that attack them.

When an armed individual is attacked, he/she does not benefit from having the aggressor jailed, society benefits. The only benefit for a victim is the swift ending of the violence.

The police work for society as a whole.

If required to stay alive, ending the life of an assailant who presents a deadly threat is not bad thing.

As for the laws in France, there are wiser minds than mine at work on just that. I hope for the best.
