I guess I don't see her, like you do, "acting like it never happened". She's been supporting TINI (the same fans who wrote the letters). She's been speaking out and concurred with everything those "followers" have said. She's challenged AEG, Kenny and Travis, all who started out saying Michael was "healthy" and in "top condition" at the onset. Now they've changed their tune. If she was all about Me, Me, Me, then why'd would she risk being excluded from the movie and exclusion from the credit she would receive by challenging the movie and its makers?
You have your right to be suspicious. I'm a NYer and I understand being suspicious of peoples nature and motives.
However, being a NYer, I also understand and recognize when someone is loyal, the lengths they will go to to protect their friends/family from people who have done them wrong. I see that in her. Okay, so I don't really think it was great taste to post photos of his resting place, but with the exception of flowers and messages being placed there, the photos are no different than the ones I found featured on another website. It looks no different than the 1952 photos that were taken of that exact same spot. Even the encasing is there back then. There's no evidence that that spot is even his exact burial spot. It could just be where they put his messages/gifts.
I tend to think that we would have heard "foul" from people like Latoya or Randy if they objected to her photos. Randy is in regular contact with Karen.
As for Prince, Karen didn't confirm anything that hadn't already been shown online. And LaToya confirmed it as well. Quite frankly, the family might not even care if the public knows...for all we know, they may want the public to know as it is a big "F-You" to all those who say that Michael isn't their biological father.
