“Even if this motion is successful, it doesn’t mean that Luigi Mangione walks out of prison,” said Ron Kuby, a criminal defense attorney whose practice focuses on civil rights. “All it means is that the items that were seized from him, or seized that belong to him, can’t be used as evidence against him.”

Kuby thinks that Mangione’s team has made enough claims in their papers to merit a hearing on the issues, in which the police officer involved would have to testify, confirming or denying the facts. “It does appear that they stopped and frisked Mangione without a legal basis to do it. If that’s true, everything that follows from there is likely to be found to be unconstitutional,” he said.
