We have become helpless sheep. That is one of the aspects that the terror attack against random workers in France highlights. If the people would have been armed, the death toll would have been much smaller: the attackers would have been quickly eliminated by some among the citizenry.
Instead we Europeans have become dependent on the dangerous "protection" of the armed forces (police, army). There are a couple of exceptions in Switzerland and Austria, where people does have the right to own arms (and where there are no terror attacks, incidentally), but otherwise that's the norm across Europe: citizens can't protect ourselves, we are strictly dependent on the state.
We need to regain the right to be armed, a proud people is an armed people. Anything else is just sheep awaiting the slaughter, regardless of who is the author.
