answer:Concurrent sentencing is usually applied when someone is convicted of charges that are similar in nature (e.g. crime A shares elements with crime B). So, it makes sense for them to use it in that case. Other times, it’s through a plea bargain. Most states put it to the discretion of the presiding judge. I’m not sure what you’re asking. Are you asking whether it’s good policy? Note: you’re kind of asking a legal question so the “legalese” is going to come in.
