“To make any plan successful we need to approach and speak with the population [...] because the population does not know immediately what to do, for example, in case of alerts. If you are on high alert what things do you need to do? You can move? Where? You can’t move? The cars should remain where they are? You have to move, you have to climb to the upper floors, you can stay on the floor below. People need information to be able to answer these questions because these are not obvious.[...] if you want to get the information in the course of the event and make the real time intervention in emergency really effective the population should be warned first, they should understand the critical issues and how to move when there are critical issues.“
