To say you can be charged with affray for defending yourself isn't just ill informed, it's a load of bollocks.
Utter nonsense.
and yet it happens. I know of a couple of cases and a quick google will find you plenty more.
I don't say things for the hell of it.
Here's a random one off google.
Can anyone offer any advice on the following,
I was recently in the local park with my family , 2 young babies & my dog , muzzled & on its lead , when we were attacked by 3 dogs , then the owner appears , & attacks me & threatens to attack my babies in the pram, I respond in self defence , using very reasonable force , he sustains minor cuts / bruising, I get arrested as he has the more visible injuries, and offered either a caution , which I refuse as I am a former licensee & hope to be again with a perfect record or as now has happened been charged with affray under S.3 public order act.
What advice can anyone offer , would this have been a CPS decision?
