  "account": "Shortly before 4 a.m. on Thursday 3 September 2026, Waymo pulled one of its driverless cars over in San Francisco's Richmond District. It had detected “a violation of our terms of service involving a firearm”. Waymo alerted emergency services and “cooperated fully” with police, a Waymo spokesperson told the Los Angeles Times (12 September). The San Francisco Police Department said officers made a “high-risk vehicle stop” and detained the two juvenile passengers. They found a loaded AR-style assault rifle, suspected marijuana and mace spray, and the two were taken to juvenile hall. The Independent, citing SFGATE, quotes SFPD spokesperson Allison Maxie calling the weapon an “AR-styled assault rifle also known as a ghost gun”. It says the boy and girl were booked into the Juvenile Justice Center on firearm-possession charges. The California Post puts the stop at 40th Avenue and Cabrillo Street. No source says how the firearm was detected; The Independent and Xataka both say this is unclear.",

It had detected “a violation of our terms of service involving a firearm”. Waymo alerted emergency services and “cooperated fully” with police, a Waymo spokesperson told the Los Angeles Times (12 September). The San Francisco Police Department said officers made a “high-risk vehicle stop” and detained the two juvenile passengers. They found a loaded AR-style assault rifle, suspected marijuana and mace spray, and the two were taken to juvenile hall. The Independent, citing SFGATE, quotes SFPD spokesperson Allison Maxie calling the weapon an “AR-styled assault rifle also known as a ghost gun”. It says the boy and girl were booked into the Juvenile Justice Center on firearm-possession charges. The California Post puts the stop at 40th Avenue and Cabrillo Street. No source says how the firearm was detected; The Independent and Xataka both say this is unclear.",

It had detected “a violation of our terms of service involving a firearm”. Waymo alerted emergency services and “cooperated fully” with police, a Waymo spokesperson told the Los Angeles Times (12 September). The San Francisco Police Department said officers made a “high-risk vehicle stop” and detained the two juvenile passengers. They found a loaded AR-style assault rifle, suspected marijuana and mace spray, and the two were taken to juvenile hall. The Independent, citing SFGATE, quotes SFPD spokesperson Allison Maxie calling the weapon an “AR-styled assault rifle also known as a ghost gun”. It says the boy and girl were booked into the Juvenile Justice Center on firearm-possession charges. The California Post puts the stop at 40th Avenue and Cabrillo Street. No source says how the firearm was detected; The Independent and Xataka both say this is unclear."

            "account": "Shortly before 4 a.m. on Thursday 3 September 2026, Waymo pulled one of its driverless cars over in San Francisco's Richmond District. It had detected “a violation of our terms of service involving a firearm”. Waymo alerted emergency services and “cooperated fully” with police, a Waymo spokesperson told the Los Angeles Times (12 September). The San Francisco Police Department said officers made a “high-risk vehicle stop” and detained the two juvenile passengers. They found a loaded AR-style assault rifle, suspected marijuana and mace spray, and the two were taken to juvenile hall. The Independent, citing SFGATE, quotes SFPD spokesperson Allison Maxie calling the weapon an “AR-styled assault rifle also known as a ghost gun”. It says the boy and girl were booked into the Juvenile Justice Center on firearm-possession charges. The California Post puts the stop at 40th Avenue and Cabrillo Street. No source says how the firearm was detected; The Independent and Xataka both say this is unclear.",
