THE JO COX MURDER CCDA investigation

I have never been able to get my head around this ,Different views to many but tbh She believed in what she was doing and was hardly a Threat to anyone

At Least she had a Belief  ,Not like half your Luvvie band wagon mob .

Why was  this so called Right Wing Nutter so Intent on Killing her, knew her route Times etc ...

At the Time My Mrs said , how is the Hubby up there giving these speeches , You would not be able to talk yet alone give speeches ....

Jo came up in our  discussions earlier , My Mrs is Left wing Always has been always will be ,Despite living with a Person she Describes as Alf Garnett ..

Tonight she says  Did JO,s husband know the attacker ,was there any investigation into that  I was stunned tbh  , I said the blokes a nutter

, she said yes the Village idiot type I then I said but surely if there was a case of another reason ,he would have said , the Reply no he Got his 5

minutes of fame

Given the aftermath and Revelations , Was MR COX fully investigated ?  Perhaps the Clock was ticking, Quite Obviously the Wheels had already fallen 
off regarding Save  the Children Etc , was JO about to fck him off out of it ?

Was any connection between Mr Cox and Mr Mair ever investigate ?
