Scary moment for NY Yankees GM Brian Cashman ... Connecticut cops had their guns pointed straight at him during a traffic stop last week -- and the terrifying incident was caught on video.
52-year-old Cashman was stopped in Darien, Connecticut last Friday after cops mistakenly thought he had stolen the Jeep he was driving.
The police footage from incident is intense ... officers pointed firearms at the Yanks exec and screamed at him to get out of the car and slowly move toward them.
Eventually, cops realized Cashman did NOT, in fact, steal his own car .
