From the way she acted on TV to the news cameras, I highly doubt that she 'legitimately knows nothing and genuinely believes her brother is innocent'. I don't buy that at all. It's a little coincidental that she flew down to Brisbane just a few days before this all happened.
If she (and the rest of the BC family) genuinely thought their beautiful GBC was innocent and wanted her to come home, surely they would have helped A LOT more than they did when she went missing. They (including GBC himself) would have given statements immediately to police and done EVERYTHING they could to help out with questioning and to also go out searching for her non stop.
This is JMO but if my wife went missing one morning and I was truly innocent and the police were treating it as a homicide, I (along with the rest of my family) would be screaming out to the public for help and we would be be out with the police in their cars scouring the local areas non stop to help find her.
We wouldn't be going to 'vacuum' houses for our business and we surely wouldn't be going down to the Gold Coast to meet with a criminal lawyer on the same day my wife disappeared if I was 'innocent'.
I'm sorry but the way the whole family has acted from the very beginning does NOT show a family that believed in their sons innocence and they quite clearly did not want Alison to 'come home' or to be found.
I fully understand where you are coming from Jam13. Your interpretation of the actions of certain people, does suggest actions that are truly wicked and unacceptable. If people have indeed colluded to cover up a murder I hope each person involved is bought to justice. However, at this point in time I am still open to other reasons for the actions of some individuals. Families have different dynamics, balances of power, and ideas of submission, respect and authority. Is there the possibility that people other than the children have been subjected to "debriefing" that could be manipulative? Could a family in crisis and shock have reverted back to "submitting to the protection and guidance of whoever naturally leads that family?" Established family patterns and culture would be hard to divert from in times of extreme crisis. These thoughts, combined with the acknowledgement that the shock of what happened to Allison would have
created a lot of grief, stress, turmoil and confusion for each individual in the family, makes me keep an open mind about some people's actions.
