On Wednesday evening, Kristersson will participate in a memorial service in Örebro.
An incident like the one at Risbergska shakes up all security issues, and it sparked an important debate, he says.
Both he and Justice Minister Gunnar Strömmer (M) welcome further investigations into the school incident, including the Ombudsman's review of a complaint filed by relatives of two people who bled to death at the school against the police.
The police's own evaluation shows there are several lessons to be learned from the incident, Strömmer says.
Not least when it comes to the very difficult question of when it is safe to bring in healthcare personnel.
