B.C. Gangster gets moved to lower security prison

The leader of the Independent Soldiers gang claimed that his Charter rights were violated. After appealing to the B.C. Supreme Court, Jayme Russell was able to transfer back to a lower security jail. Prior to the appeal he served a seven year sentence for two trafficking convictions.
This article relates to Law 12 because we were recently discussing how Charter rights get violated. I wonder if there are more punishments than just a sentence to jail.. What are the differences in a high security and low security jail other than the security?..
