Slipping into the abyss of fear?

The incomprehensible violence in Canada over the last couple of days is tragic. My heart goes out to the victims and their families. Those events show us how vulnerable we all are. I keep asking myself ,WHY? Can these episodes be stopped? How? When will they stop? What is their goal? Is there a political solution?  We must find a core solution to the crisis of ISIS. We cannot wait years and years.My family coat of arms,perde sed caute the latin for fight with caution sometimes is applicable;but in this instance, we must fight with a very heavy hand using all of our available resources.
