So will every business, school and public place need trained bathroom police to check birth certificates?  Sounds like carding people who buy booze or tobacco, where it is the law to card everyone ... because ya never know if someone looks older than they are.  Same with bathroom police, would have to ID everyone because ya can't tell 100% by looks what gender is standing in front of you.  And what if someone has to go really bad and forgot to bring his/her ID?  Will there be a requirement for bushes to be nearby bathrooms in case of no ID?
