As the investigation continues over the motivation of cop killer Ismail Brinsley and his ambush of NYPD officers Wenjian Lu and Rafael Ramos, new evidence has surfaced. A past post was pulled from his Facebook page before it was deactivated. The post is cellphone footage of police attempting to search Brinsley on a bus. A drug sniffing K-9 unit allegedly hits on Brinsley’s bag and the officer wants to search the contents of the bag. In the video, Brinsley objects to the search and the police officer demands Brinsley stop recording.
