What about child abusers? People convicted of fraud or other types of corruption? etc. Basically people that never should never be allowed to do certain types of work because it wouldn’t be in the public interest?
I'm not sure, actually. The law doesn't seem to specify, although it does say exceptions can be made, so I figure that's what happens. Estonia has also been known to deport its own citizens when they truly are a menace to our society.
