You're going to have to explain what "major doctoring" is, because I haven't seen that really harped on by anyone except a select handful of people here.
Also, if you think those pictures didn't get out around the internet and have an impact, you're mistaken. This is 2012 - Twitter and Facebook reach more people and reach further than any news source could hope to reach. That's why social media managers get paid big time dollars from corporations, etc. these days.
Were the photos of Zimmerman doctored? Are you talking about photos released by the media, and media coverage of the story?
They're more similar than anyone would want to believe, at least as far as public reaction/outcry, etc. But it would take someone looking from the outside as objectively as possible to see that.
What photos? This question doesn't make any sense to me.
