Finnish Criminal Policy: From Hard Time to Gentle Justice (https://epublications.marquette.edu/cgi/viewcontent.cgi?arti....)
> From a post war crime boom and relatively high incarceration rates, Finnish prisons have emerged to be counted among the most humane correctional facilities in the world and yet, recidivism is very low compared to international standards.
Sounds similar to that of Norway which is known for its kind/compassionate treatment of prisoners.
"Lax" is probably not the term here, given the low recidivism.
Perhaps "effective".
Thanks, changed it.
