Secret ID vs Public ID
I've been more of a lurker lately than a poster , but here's my two cents .
A Secret ID for public employees is quite possible . We do not show the faces of Undercover Agents , SWAT , or , Detectives , because it endangers them on and off the job . Being recognized by chance as a Silver Avenger may endanger you , your mission , and innocent bystanders . Making you a danger to the public and preventing any public relations work . I mean what school would want a SA speaking in their school , leading their scout troop , or protecting someone else when they themselves are a target .
A Public ID does make the public and the media more open to them , but also more critical of individuals and used as political chips in the game . Instead of being SuperCops they become SuperTargets .
