A court filing publicized late last week drew outrage on Monday over the case of Ismael Lopez, a 41-year-old man who was killed by police two years ago in Southaven, Mississippi.

To avoid responsibility for the man’s death, attorneys for the city are arguing that Lopez had no constitutional rights due to his status as an undocumented immigrant—blatantly contradicting U.S. law and numerous rulings by the U.S. Supreme Court. Kristen Clarke, executive director of the Lawyers’ Committee for Civil Rights Under Law, was among the immigrant rights defenders who drew attention to the case on social media.

Lopez was shot in the back of the head when the police came to his home, where he’d lived for 16 years, in July 2017. His widow, Claudia Linares, filed a wrongful death lawsuit against the city of Southaven this past summer, a year after a grand jury declined to indict the two officers involved in his death.

Southaven officials argued in a court filing revealed late last week that Lopez did not have Fourth Amendment or 14th Amendment rights—leaving him without protection from unreasonable search and seizures or equal protection under law.

“If [Lopez] ever had Fourth Amendment or 14th Amendment civil rights, they were lost by his own conduct and misconduct,” reads the court filing. “Ismael Lopez may have been a person on American soil but he was not one of the ‘We, the People of the United States’ entitled to the civil rights invoked in this lawsuit.”

Murray Wells, Lopez’s family’s attorney, called the city’s claim “chilling,” “insane,” and “ludicrous” in a press conference on Thursday.

“They were residents that the city should be protecting and now that city is directly attacking their very own residents,” Wells said. “For 16 years they were happy to take tax money. Happy to let these people spend their money at the store, happy to let them participate. But when [the police] make a mistake now these residents don’t have any legal recourse. It is chilling.”
