You are rightly angry and allowed to feel how you do considering what you went through. I am so sorry that happened to you.
However, crime is not about emotions. It's about understanding motivation, prevention, punishment, recidivism, ACE and so many other things. To take your points one by one.
Reading the youth sentencing guidelines online has infuriated me. Not only is the maximum punishment significantly different, but then they take into account whether the criminal came from a deprived background or has family issues etc!
ACE (adverse childhood events) shape children. You can pretend they don't but they are a very accurate way to predict the likelihood of a person offending (plus their sex, obviously). Children with multiple ACEs are much more likely to offend. And since children are children, they have had no chance to escape these ACEs in their home. Sentencing a child to prison is just giving them another ACE, probably several. Making it vastly more likely they will spend their life reoffending repeatedly. Yes, they are punished. No, it won't reduce reoffending or psychological damage.
FFS, a lot of people including their victims go through the exact same yet don’t turn to a life of crime.
There are lots of reasons for this. The age ACEs happen, the number of ACEs, protective factors like involved parents or other safe adults, brain plasticity, poverty, peers, sex, race, area, diversion things like youth programs, all things children have very little control over.
It’s just ironic that as a “youth” he was confident enough to decide to commit multiple robberies in a callous and cruel manner - but now gets his hand held throughout the process and a likely slap on the wrist to make sure he’s okay.
It's not ironic. It's a reflection of justice, rather than revenge.
If you want to reduce offending and particularly youth offending, we need lots of really important things to happen. More funding for children's programs, schools, DV provision, healthcare, policing so many things. But locking more children up for longer will increase offending. Not reduce it.
Again, horrible, traumatic thing that happened and anger is completely understandable. And it's much easier to be angry at him than his abusive father, disinterested mother, the people who were violent around his, the policies that reduced his chances, the schools that failed him because of funding, the closed sure start centre, the drinking in his pregnancy and on and on. But that sort of thing is to blame. As much as he is.
