  "account": "Just before 4 a.m. on 8 November 2023, a passenger on a Metro bus in Hollywood reported an armed man aboard. The bus was at Melrose and Western avenues. The driver pulled over and evacuated the other passengers. Officers got no response from the man, and a two-hour standoff followed (Los Angeles Times via Police1, 9 November 2023). The LAPD sent in its Boston Dynamics Spot quadruped. Its camera confirmed the man was asleep with a gun (Police1). The LAPD's quarterly report to the Police Commission says the robot was a barrier between suspect and firearm (NBC Los Angeles, 8 March 2024). The man woke, left the bus and was taken into custody about 6:40 a.m. The weapon was a BB gun (Police1). Deputy Chief David Kowalski approves each use. The robot cost nearly $300,000 (NBC). International Business Times' October 2024 account says the robot removed the gun.",

The LAPD sent in its Boston Dynamics Spot quadruped. Its camera confirmed the man was asleep with a gun (Police1). The LAPD's quarterly report to the Police Commission says the robot was a barrier between suspect and firearm (NBC Los Angeles, 8 March 2024). The man woke, left the bus and was taken into custody about 6:40 a.m. The weapon was a BB gun (Police1). Deputy Chief David Kowalski approves each use. The robot cost nearly $300,000 (NBC).

The driver pulled over and evacuated the other passengers. Officers got no response from the man, and a two-hour standoff followed (Los Angeles Times via Police1, 9 November 2023). The LAPD sent in its Boston Dynamics Spot quadruped. Its camera confirmed the man was asleep with a gun (Police1). The LAPD's quarterly report to the Police Commission says the robot was a barrier between suspect and firearm (NBC Los Angeles, 8 March 2024). The man woke, left the bus and was taken into custody about 6:40 a.m. The weapon was a BB gun (Police1). Deputy Chief David Kowalski approves each use. The robot cost nearly $300,000 (NBC). International Business Times' October 2024 account says the robot removed the gun."

The driver pulled over and evacuated the other passengers. Officers got no response from the man, and a two-hour standoff followed (Los Angeles Times via Police1, 9 November 2023). The LAPD sent in its Boston Dynamics Spot quadruped. Its camera confirmed the man was asleep with a gun (Police1). The LAPD's quarterly report to the Police Commission says the robot was a barrier between suspect and firearm (NBC Los Angeles, 8 March 2024). The man woke, left the bus and was taken into custody about 6:40 a.m. The weapon was a BB gun (Police1). Deputy Chief David Kowalski approves each use. The robot cost nearly $300,000 (NBC). International Business Times' October 2024 account says the robot removed the gun.",
