Motorbiking's hostility towards refugees is well known. It's also obvious that he will wilfully misrepresent factual data.
In those respects his claims and assertions deserve scrutiny.
For instance, he claimed that the refugees were found 7 nautical miles from Calais, they weren't, they were found about 9 nautical miles from Calais. He claimed it was inconceivable that the bodies could have drifted back into French waters to 7 miles form Calais, but the dividing line is only 10 nautical miles from Calais, at that point. It's easily conceivable that the bodies could have drifted less than 1 nautical mile over a 12 hour period.
He claimed it was Southerly wind, it wasn't it was a Northerly wind.
He claimed that the tide was HW-1 at Dover when they entered the water, it wasn't it was LW at Calais, that means it was about HW-5 at Dover.
He claimed that they entered the water at about midnight, they didn't they entered the water at 20.00hrs.
Clearly Motorbiking's claims deserve to be scrutinised.
We are still awaiting the outcome of the official investigation.
Of course if someone's claims and assertions, based on their prejudice, are congruent with your own, you'll be more than content to accept their opinion without question.
