While there's a hard block on using emotion recognition in workplaces and educational institutions, the other cases you list are listed under "High Risk" and so they are very much included in the regulation.

There are several exceptions for different kinds of law enforcement, things like eminent danger, or doing biometric filters when searching for someone that fits a description. How much you can squeeze in under those exceptions depends on how bold the police are. Probably a lot, but it's not written that way.
