JK Rowling apologises over Trump disabled boy tweets per BBC News neither of whom seem to have the gift of sight or any class

The BBC report JK Rowling's mealy mouthed apology for her recent factually incorrect tweets about President Donald Trump:

'"Multiple sources have informed me that that was not a full or accurate representation of their interaction.

"I very clearly projected my own sensitivities around the issue of disabled people being overlooked or ignored onto the images I saw and if that caused any distress to that boy or his family, I apologise unreservedly."

Rowling didn't apologise to Mr Trump himself.

...

Mr Trump is said to have shaken the boy's hand as the president entered the room.'

Some points:
First, why didn't JK Rowling apologise to President Donald Trump? He was the person whose actions she misrepresented. It was his actions that she decried. Yet it's the child and his family that get the apology. Can't JK Rowling being herself to apologise to the injured party? 

Second, the BBC inform the public that 'Mr Trump is said to have shaken the boy's hand as the president entered the room.' I've seen the video showing just that, it's very easy to find on the Internet.

Have the BBC really not seen the video or are they happy to cast doubt on the actions of President Donald Trump and so support their fellow lefty JK Rowling?

BBC bias as usual? 

Here's the video that proves JK Rowling incorrect

How can the BBC continue to simply state that 'Mr Trump is said to have shaken the boy's hand as the president entered the room.' 

'Mr Trump is said to have...' It's there on video, surely the wording must be changed to 'Mr Trump did shake the boy's hand as the president entered the room.'
