Is it illegal to wear a US special police uniform in China? Shopping on the street? How about going to a tourist attraction?

There is no law that forbids you to wear foreign standard clothes on the street, but I think if you walk in the street in this dress, there will be a police uncle who will ask you to take it off. First of all, if you wear such clothes, if others don't think you are a policeman when you walk and ask for help, in what capacity will you save people? Compared with the police, your ability is limited. If there is an accident, whose fault is it? But also mislead people and affect the work and image of national civil servants. Personally, I think it's best not to bring a gun or a helmet when going out.
