[User] 能否帮我统计特定车站(station_id 为 'station_xyz')的所有工作人员数量？

[Assistant]
MATCH (s:Station {station_id: 'station_xyz'})<-[:BASED_AT]-(staff:Staff)
RETURN COUNT(staff) AS total_staff

[User] Can you narrow this down to only show cases where the case type is 'Criminal'?

[Assistant] SELECT case_name, case_number, date_opened FROM legal_services.cases WHERE lead_lawyer_id = 'lawyer_abc' AND status = 'Open' AND case_type = 'Criminal';
