jeesus del boy - is there any situation with your family that doesnt end in violence? 
"went down to tescos for a packet of fags, guy looked at me funny - bosh."
"then my eldest took the hump and gave the guy in front a right doing cos he was holding up the queue looking for change"
etc....
you do know that most people go through life never hitting anyone right? 
Del, I count you as a friend and in that spirit I will voice the following observations and advice. Please take it that way.
What BJ states above is actually spot on. You and your family do seem to resort to violence far too quickly, even IF it is justified, IF at all!
So for that stupid act by a third party of spraying Coke onto your cars, which is bloody annoying, your son got involved in violence. Physical assauly, GBH, once convicted can put you away for up to 5 years. Will you and your son think that was worth it for a bit of Coca Cola on your cars?
You often express a distrust of the police and complain of them harrassing your son, or if I remember correctly, falsly arresting him. I do work on and off with Kent Police and the CPS, and I know that if an individual plays with fire they get burnt, and what you complain of happens Del.
My advice to you is for you all to wind your necks in and be sensible. Play by the law and you all will not risk everthing for one heated, OTT, act.
Just trying to be constructive here Del
