If anyone was in a position to get police protection if he was feeling threatened it is him.
Why did he not stay put and have his niece on standby to travel to them?
Why did drive that far to test his eyesight, and why did he not just turn round and drive back once he was happy that he could drive?
Will his insurer be happy about him getting into a car when he thought there was a problem with his eyesight?
Why did the child not just have a wee and get straight back into the car?
Why didn't his wife drive given she clearly was only briefly incapacitated?
One of the main messages was not to travel to other areas in order to avoid increasing demands on healthcare where you travelled to. This is illustrated by Cummings travelling, staying and then needing an ambulance and an overnight stay in hospital for his son.
Clear that he doesn't think the rules apply to him. If the rules had allowed that much leeway the public would have behaved very differently.
