## Prediction

Over the coming 24 hours, Muslim communities in the United States—especially in California and large metro areas—will experience heightened fear, increased self-imposed restrictions on public religious activities, and localized community patrols. Civil rights groups will report a surge in threatening messages, harassment, and online hate. While widespread physical violence is unlikely immediately, there is an elevated risk of sporadic assaults or vandalism targeting mosques and Islamic centers. Community organizations will urgently coordinate with law enforcement on protective measures.

## Drivers

- Neo-Nazi terrorist shooting at the Islamic Center of San Diego with multiple fatalities
- Live-streaming of the attack amplifying psychological impact and copycat risk
- Historical patterns of backlash and hate incidents after high-profile terror events
- NORTHCOM note of acute domestic terror and intercommunal tension implications
