Dave: If they moved "it has been alleged" to the start of the comment yes, they would need to re-write it slightly, such as by adding 'that' after 'alleged'

Steve: We have to forgive journalists somewhat as they have to cover their arses for fear of being sued!
The easiest way to avoid being sued is to quote the truth. 'Weasel words' are only required by those who rush to print without first checking their facts/sources.
