Czech schools have increased security in recent years, adding chip card entrances, turnstiles, and cameras, though experts say attacks can’t be entirely prevented. Jiří Zajíček, chairman of the Union of School Associations, stressed that while schools do their best, 100 percent safety is impossible. Experts emphasized the need to address mental health and teach conflict resolution. Monday marks ten years since a fatal school attack in Žďár nad Sázavou.
