How will the Kraków attack change Poland?

The attack marks a turning point for Poland, writes Michał Szułdrzyński, deputy editor-in-chief of Rzeczpospolita:

“Until now, such an attack had been unimaginable to us. We would board a bus or enter the underground and be absolutely certain that, barring some random accident, we would reach our destination safely. Today we must realise that attacks will change our lives and our perception of public safety. The images from Kraków show us that we as a society have no idea how to behave in such crisis situations. … The world as we knew it is now a thing of the past. When I think back to the carefree youth I spent in Kraków’s Main Square, I know it won’t be easy. But we have no other choice.”
