I know 99.9% of you are not lawyers, and I'm not really looking for advice as I have a reasonable idea of what the law allows up here. What I'm looking for was places I could go hunting to build a set of resources to stand on should I ever be confronted by someone about taking photos in a public space.

Does anyone know a good place to look for legislation or actual legal information about this? Everything I find is people who are not lawyers, I'm looking for actual government published information I could possibly take to a lawyer later to build something solid I can present if I ever find myself being bullied / pressured by those who don't know what's right.
