Should Reuters be censured in some way for deliberately modifying photos to promote a specific agenda?

It has recently been revealed that Reuters modified multiple photos to hide violent behavior on the part of the “peace activists” on the recent blockade busting flotilla. Here is evidence from Reuters’ own website, more analysis of the same photo from a blog, as well as more cropped photos. Sadly, this is not the first time Reuters has been caught manipulating photos this way. So, what kind of repercussions should Reuters suffer? Is there any way to trust their “unbiased reporting” again?
