There is no conclusive proof (yet) that the McCanns did it. There is no conclusive proof (yet) that there was an abduction. IF the McCanns did it, they are not victims, they are perpetrators. IF it was an abduction, the McCanns put her in harm's way by their own negligence/studpidity. While that doesn't excuse the abductor's actions/guilt, it doesn't change the fact that they failed to do their job as parents. Madeleine is the victim here, as are the twins. What if she had died in a fire or some other accident because she was left on her own? Would we be seeing them as victims then? And they have repeatedly justified that behavior, saying they were responsible parents. They had an opportunity to educate other people about how to keep their children safe, but they can't admit their own failure in this regard that they weren't responsible to leave 3 children under 4 alone in an unlocked hotel room where they couldn't see/hear them.
Given the lack of conclusive proof, people are going to look at their behavior such as the smiling. Or blogging about haircuts & jogging. Or releasing photos of one's own wedding/communion. Does any of that prove their guilt? No. Does it raise suspicions among many of us? Yes. To me, that seems more like people seeking publicity for its own sake or trying to win our sympathies, at best. At worst, it may be intended to distract our attention from their possible involvment. I was inclined to believe the parents' innocence at the beginning. But their behavior is leading me to doubt their innocence.
The police have to look at all the evidence, even if it might incriminate the parents. In fact, I think what the PJ did wrong was not considering all possibilities (parental involvement as well as abduction) from the start. That might have preserved evidence which may have either cleared or implicated the McCanns. Everyone at the resort should've been thoroughly interviewed.
So, I think the main question is what is the best way to bring Madeleine McCann home safe (if she's alive) or bring those responsible to justice if she isn't alive?
Apparently, the local police in the UK are going to ask her the 40 questions she wouldn't answer:

That's a good start. I consider it reasonable to be nervous about answering questions in a foreign country where you don't understand the laws, but now she's home & it's the local police/legal system, she should be more co-operative. If not, that's very telling in and of itself.
