I worked for several years in debt recovery which often meant liaising with County Court bailiffs.
I found them mostly to be polite and realistic and never received one complaint from a debtor about their attitude when executing warrants. Most had no saleable goods anyway!
They have a very difficult job and sometimes face open hostility for simply acting on an instruction.
In this case, the bailiff concerned got it badly wrong and he has held his hands up. No consolation to the victims I know but I'm sure he will be given a reprimand and the negative publicity will be costly.
If it had happened in my home I'm sure it would make my blood boil though I don't think I would resort to violence!
