Polish Prime Minister Donald Tusk has called for stricter regulation of online spaces in the wake of the deadly shooting in Krakow, warning that what happens online can affect people's thoughts and actions as strongly as events in the real world.
He revealed that the Krakow shooter had undergone psychological tests less than a year earlier when applying for a gun permit.
Recognizing that authorities cannot create a "perfect world", Tusk stressed the importance of keeping Poland among the safest countries, describing the attack as the first of its kind and calling for action to ensure "it is the last".
