Four months after masked federal agents shot and killed Renee Good and Alex Pretti on the streets of Minneapolis, New York leaders announced a plan to implement some of the strictest rules for immigration officials of any state in the country.

The package, which is included in the state budget deal announced on Thursday, prohibits state and local officials from entering into formal or informal cooperation agreements with Immigration and Customs Enforcement, and forbids law enforcement agents from wearing masks.

The rules also prohibit ICE from using local jails to house detainees and from searching New Yorkers’ homes, hospitals, churches and schools without a warrant signed by a judge. But they will not affect the ability of law enforcement officials to coordinate with the agency on public safety issues.

Gov. Kathy Hochul said on Thursday that the changes were necessary given the extent of the Trump administration’s immigration crackdown.

“They didn’t just target hardened criminals and gang members, which I would have supported — we did support,” Ms. Hochul said. “They also targeted mothers still nursing their infants, separating them, an 85-year-old widow in her nightgown.”

She said that ICE had used intimidation tactics to evade responsibility, adding: “New York will no longer stand for it.”
