inciting violent disorder, yes, the penalty was harsh, yet I do think all crimes should get a tougher sentence as that is the only way people learn, plus in certain crimes if not from England originally then deported back to your original country regardless of if you fear for your life back from where you come from.
Love the law in Australia, "if a non-citizen is sentenced to 12 months or more imprisonment, or if they are convicted of certain serious crimes like those of a sexual nature involving a minor, their visa can be mandatorily cancelled, leading to deportation. Additionally, even for crimes not carrying a mandatory cancellation, the Minister for Immigration has the discretion to cancel a visa based on character grounds, which could also result in deportation".
