Caporegime
I'm thinking it needs someone with more substance than you've got there to sell a pitch for a life (or however long you believe) sentence for what he initially got jailed for as a teenager.
You're frothing about wanting a massive sentence while judging his actions retrospectively.
That's not how justice works so it needs you to explain how a massive sentence gets justified before the evidence to support it exists.
He got 3 years 4 months for collecting information and talking in favour of violent terror crime at the age of 18. That sounds like hard time for words but so be it.
According to your pre-crime punishment thinking, this should have been a life (or however long you believe) sentence because he later did commit a violent terror crime.
Again, Einstein, nobody mentioned pre-crime punishment - learn to use your eyes and actually read. I know you may find it hard, but please do try. He was found guilty of a terror related offence and let out of prison after only a year of a 3 year sentence and went on to commit this crime. We also had the last anus who went out and killed people released earlier than the full term allowed. That ended well, didn't it.
The maximum term, for minor terrorism offences, I believe is 6 years. Judges can start firing that out instead of 3. Maybe then they'll have time to go through some conditioning.
