Never mind what Seven has said. His opinion doesn't exactly represent that of the entire Western Europe. That being said, he's not entirely wrong. These kind of things are an anomaly and rarely occur in Europe.
Largely due to the tough gun laws. For your information, Finland has the 3rd highest gun ownership in the entire world, only surpassed by the United States and Yemen.
Also, for your information you could have come at Seven on this issue a long time ago, as a psycho killed 18 people in Germany back in 2002.

As as bridges are concerned, Seven's right about Portugal not being exactly counted as "Western Europe". Not to mention Portugal is one of the poorest countries in Europe so it's not a surprise their infrastructure isn't up to par.
PS: It should also be noted that the difference in reactions (of school shootings) between European countries and the US is extremely big. Unlike the US, where it takes years and years of school shootings and innocent children to die, to make a change in laws changes in Europe are almost immediate. This is one of the biggest 'massacres' in Finnish history and already they are in the process of changing their gun laws; just three days after the incident!
