Radicalization is recognizable, but without a well-functioning warning system, it is much harder to prevent tragedies.

Following a deadly attack in Krakow, former classmates discuss the perpetrator's troubling behavior, including violent drawings and an interest in history and firearms. Authorities often overlook such signs, especially when the individual has no criminal record or ties to extremist groups. Expert Attila Suhajda emphasizes the importance of community awareness in recognizing radicalization indicators. The attacker had a fascination with military culture and shared disturbing imagery online, including references to past terrorist acts. These warning signs should be taken seriously to prevent future violence.
