Not legal advice. This range is the statutory penalty as written in the law — it is not “your sentence.” What is NOT accounted for here: Priors, further-offence intent, plea, discretion, aggravating/mitigating factors, damage actually caused. If you face a real charge, consult a licensed lawyer in the relevant jurisdiction.
