The post you are reporting:
The idea is, that many people who are now in custody for rioting, even if they get an appeal through after the initial sentence and have a few months taken off, will not be let off lightly if they are caught again committing a crime.
They know this, or will know it once the judge has spoken, and after having spent a spell in prison.
These people now have a criminal record, many of them are probably sorry, so the idea is, to make sure as many of them are brought to justice and as few as possible get away with it by going undetected.
The Police will be probably examining films in months to come, to find the culprits. In this sense, Gov. has got the message over, that there is no amnesty for what happened.
