San Francisco police officers pepper-sprayed, dragged, and smashed their way into a car during a Fourth of July 2024 arrest that never should have happened, all because someone typed a license plate number incorrectly into a patrol computer. Matthew Ludwig, the man on the receiving end of that violence, would not live to hear the city's police watchdog confirm what he had said all along: that officers wrongfully targeted him, escalated without cause, and used force that could never be justified.
According to KRON4, SFPD officers had entered Ludwig's license plate number incorrectly into their computer system, leading them to wrongly determine he was driving a stolen car. Officers initiated the stop without activating their patrol vehicle's lights, then jumped out behind Ludwig's car while it was stopped at a red light, the outlet reported. What followed, according to the station's reporting, was a violent escalation: an officer threatened Ludwig with pepper spray, opened his unlocked car door, and dragged him onto the street by his sweatshirt hood while his left arm was pinned underneath him.
Officers went on to pepper spray Ludwig in the face, smash his car window with a baton, and place a knee briefly on his head before handcuffing him, per the same account. Only after Ludwig was already in custody did officers realize their identification of him had been mistaken.
Watchdog Agency Details a Pattern of Policy Violations
The San Francisco Department of Police Accountability reported in March that two SFPD officers used unnecessary force and violated multiple department policies during the arrest. The civilian oversight agency determined that officers cited Ludwig without cause, inflicted violent force on him, and committed improper conduct by using pepper spray improperly, according to the KRON4 report. The DPA operates independently of SFPD's budget under a 2016 city charter amendment, and Section 4.136 of the San Francisco Charter mandates that it investigate public complaints against officers, according to the City of San Francisco.
The findings point to violations of SFPD General Order 5.01, which mandates that officers prioritize de-escalation and apply force only when reasonable and necessary to achieve a lawful objective, a standard the department describes as stricter than California law, per the San Francisco Police Department. When DPA sustains misconduct findings, department rules require that the case be forwarded to the police chief for suspensions of up to 10 days, while cases warranting longer suspensions or termination go to the civilian Police Commission for formal trials, the city notes.
Charges Persisted for More Than a Year
Despite the questionable legality of the stop, the San Francisco District Attorney's Office charged Ludwig with resisting arrest and reckless driving, and prosecutors refused to drop the case even as it dragged on. Prosecutors ultimately dropped the charges in September 2025, but only after Ludwig had died that same month. Under California Penal Code Section 148(a)(1), a conviction for resisting or obstructing an officer requires prosecutors to prove the officer was engaged in the lawful performance of duty at the time of the encounter, according to Shouse Law Group — a standard that becomes difficult to meet when the underlying stop itself was based on a data error.
The San Francisco Public Defender's Office defended Ludwig against the charges, and its Integrity Unit, led by Brian Cox, filed a complaint on his behalf. Ludwig lost virtually everything he owned in the aftermath: his car and property were impounded after the arrest, and an RV he shared with his girlfriend was towed a few days later, taking his remaining possessions with it.
Attorneys Say the Violence Was Never Justified
Brian Cox said Ludwig was not alive to see the Department of Police Accountability confirm he was grossly mistreated. “Nothing justified the amount of violence SFPD officers used on Matthew Ludwig,” Cox said, adding that the case showed police could wrongfully target someone, unnecessarily escalate an encounter, and take away that person's freedom. Cox also said Ludwig showed tremendous courage in exposing the misconduct.
Brandon Coleman, who represented Ludwig, said the officers involved did not know the harm their actions caused. Public Defender Mano Raju called on SFPD leadership and the city's Police Commission to implement measures preventing further misconduct, and commended Ludwig's bravery in bringing the abuses to light. Ludwig himself had said he felt the world lacked compassion for human life, and that he had never been given a fair chance.
A Watchdog Under Its Own Scrutiny
The finding lands amid unusual turbulence inside the agency that produced it. In September 2023, DPA Executive Director Paul Henderson told the Police Commission that an internal audit had revealed systemic officer errors and misreporting when logging stop and demographic data into state databases, a documented pattern that predates the mistyped plate that upended Ludwig's life, according to the SF Standard. A year earlier, DPA had told the Police Commission that nearly 60 percent of SFPD's 121 Department General Orders had not been revised since the 1990s, according to Mission Local.
DPA has also clashed with the District Attorney's Office over access to evidence: in December 2023, the agency asked the Police Commission to intervene after DA Brooke Jenkins refused to share police records and body-camera video from open investigations with DPA misconduct investigators, the SF Standard reported. In March 2026, a former DPA policy director filed a lawsuit alleging financial mismanagement, retaliation, and a hostile work environment under Henderson's leadership. The following month, the Police Commission scheduled rare performance evaluations for both Henderson and SFPD Chief Derrick Lew after it emerged that neither position had been reviewed in nearly a decade, according to Mission Local.
The case adds to a string of controversies over SFPD's use of force at high-profile moments, including the mass arrest of 113 people during the unsanctioned Dolores Hill Bomb skateboarding event in 2023, which drew demands for independent oversight, as Hoodline previously reported.
