I agree that we should challenge all potential miscarriages of justice. It could well be that there are many (of less tabloid interest) who were incarcerated even though innocent. There most likely are. It’s happened before. All of these cases matter because they point to quite scary issues within our justice system and that affects all of us.
The halo effect doesn’t actually work in the way you describe though. The halo effect works if, say, a pretty young woman needs help with a broken down car. However, if the finger of blame is pointed at a pretty young woman for something like this our press goes crazy and she is instantly assumed to be guilty by everybody. It’s immediately ten times as salacious. I haven’t heard a word of support for her, only disgust and horror, until this one article came out vs the 10,0000 Daily Mail ‘Baby Killer’ articles we’ve seen thus far. Our press, especially the tabloids, love an evil woman story. It sells.
It is therefore true that LL probably has had more press coverage than many, but I’m sure we can all agree that the vast majority of it has been extremely salacious and condemnatory. I don’t believe that anyone has issues with her conviction now because she’s young and pretty. On the contrary our society loves to string up a young pretty woman, particularly for gruesome crimes like this. If it was popular to have sympathy for such a woman we would see articles reflecting that, but we don’t. At least I haven’t and I’d challenge anyone to produce one. The press know what the public want to see and that hasn’t been in any way sympathetic to her thus far.
All that aside, if there are issues with the conviction they should be examined regardless of that. If there is a miscarriage of justice here that is still a huge issue regardless of whether or not there is much more press interest in this case vs another. I would say the same no matter what she looked like. We should be arguing the points raised and not circling around this issue, which is wholly irrelevant to whether or not she was wrongfully convicted.
