Two teens radicalized online shot and killed three people at San Diego's Islamic Center. Cain Clark (17) and Caleb Vazquez (18) were found with 30 guns and a crossbow. Their writings showed extreme hate toward Muslims, Jews, LGBTQ+ people, and Black communities. Security guard Amin Abdullah fought back, stopping the shooters from reaching 140 schoolchildren. He called for a lockdown on his radio before dying—a sacrifice praised by leaders. The attackers wrote 'Muslims should be exterminated' and used symbols linked to white supremacists. This attack happened as hate crimes against Muslim and Jewish communities rise. Imam Taha Hassane called the victims 'heroes,' saying, 'We are here to celebrate our community’s unity.' Neighbors describe the teens as once-friendly, highlighting how online hate can destroy lives. Families mourn while the community stands strong.}
