this is a media interview with a prominent criminal lawyer
The newswoman asks him if, based on his experience, he believes that a solution to the crime is close at hand. He responds by saying that "it could be that it wasn't three criminals (who committed the crime), and we may have another version of (i.e. a different solution to) the crime." He hopes that this isn't the case.
Then they have a discussion about the maximum legal sentence for the murderer. He says the maximum sentence is "life sentence". The newsman asks what does this mean in practice (i.e. in reality), how long behind bars? The lawyer says it would be 16 years, which, he says, isn't a real "life sentence." Then he talks at length about how the sentencing system in Greece is too lenient and needs to be improved and become stricter, and in his opinion Greece needs a better life sentence system, similar to the U.S., where dangerous criminals are evaluated as to whether they are a danger to the community/society before they are released.
