Garofano, Glenn vs City of Ny, et al.
Case # 23CV01676, U.S. District Court - Eastern District NY, March 9, 2023, ended September 18, 2023
$49,000 Settlement
Complaint
Description: On March 15, 2022, the Plaintiff, a 68 years old, partially disabled person, was taking a walk at 1.30 AM when he was mugged and called 911. Instead of treating the Plaintiff like a crime victim, the PO's called an ambulance and forced the Plaintiff to be taken to the emergency room for psychiatric evaluation and possible admission. On the same day, the Plaintiff was discharged by the hospital because there was no basis for the Plaintiff to be admitted or confined for psychiatric reasons. The same evening, the PO's searched the Plaintiff's home without a warrant and alarmed the second Plaintiff, who has multiple sclerosis as well as alarmed the Plaintiff's 95 year old mother.
