and this may be their mindset on why they are continuing to purse this even in the face of new evidence. the thing is-the lawyer they have makes his money off cruise line settlements, not off design changes a cruise line might agree to do. he takes cases on a contingent basis and probably, if the parents are truly doing this to get changes made, sold them on doing this case the way it's proceeding b/c 'the only way you will get the cruise line to make changes is to hit them where it hurts most-in their pocketbook; when they do a big payout the won't want to do it again and will make those changes to save money'.
reality is-even if the parents start to see/accept what most of us viewing the video believe, they may be unable to drop the lawsuit. contingency attorneys commonly have it written into their client contracts that if the client decides to drop a case they are on the hook for all the accumulated expenses plus billable hours. you look at how much time that attorney is spending with the media alone-it's got to be a massive dollar total. if they continue on and the courts dismiss the case then it's no money out of their pockets, just a financial loss for the attorney. unless they are stinking rich they may get to the point where there's no turning back on cooperating with the attorney on the case despite any level of reality about the circumstances of their child's death that they've privately reached.
