Like 1-6months but most likely a fine. Most of the major stuff I did like stealing, breaking and entering, burning someones shed down, holding my 70-80year old neigbour hostage in his own house (yes that happened) even wanking in public all happened when I was under 16.
I was caught for the hostage thing and 1 breaking and entering. Though we didnt tie him up we just barracaded his bedroom door.
