The term “similar circumstances” is a very loose term and in a courtroom specific details about the crime are taken into consideration and have an effect of sentencing. You can keep trying all you want to make the article say what you want it to say but without the specific details about each case you haven’t actually PROVED ANYTHING. Two people charged with the same crime can have two completely different sentences based on the nature of the crime. For example two people can be convicted of assault, one might receive a stiffer sentence for inflicting more harm on the victim than the other. One might receive a stiffer sentence for fleeing to escape. One might receive a stiffer sentence for pleading innocent instead of pleading guilty. One might receive a stiffer sentences based on the demographic of the victim, for example if the victim is an elderly person. One might receive a stiffer sentence for the reason why they attacked the victim. Your article doesn’t specify what exactly is considered to be “similar circumstances”. Does it mean they were both charged with the same crime? Does it mean they have the same number of crimes? Does it mean they both pled innocent or guilty? Does it mean they both inflicted the same amount of harm on the victim? Does it mean they both attacked someone of a similar age? Does it mean they both attacked the victim for the same or similar reasons? If my daughter is dating some guy and he slaps her and I go find him and beat the snot out of him I get charged for the same crime as someone who attacked an elderly person for no reason. If I hit the guy in the face one time I get charged with the same crime as someone who, for no reason, breaks an elderly person’s arm or put them in the hospital. The charge is the exact same, but the details of the crime MANDATE a stiffer sentence. The article doesn’t tell us ANYTHING about specific details of any crime, it’s an overgeneralization of the fact and DOESN’T GIVE ANY OF THIS INFORMATION THAT IS ABSOLUTELY CRUCIAL FOR SUPPORTING YOUR CLAIM. So again YOU HAVEN’T PROVEN ANYTHING.
