I was merely trying to put myself in there place, it wasn't as I personally would think. The talk on Bristol post was about bags and that JP had found them in her garden and called the police. This conversation involved her sister, though the post was removed later. Looking at the police activity there at the time, the police were collecting all bins and black bags from neighbouring properties. I think it is possible that they realized the police were closing in and they couldn't move her without being seen so in desperation used bin bags. Dustbin day was due soon so they hoped it just looked like normal rubbish. MOO I don't think anyone involved at this point would have had the ability to think rationally. They were desperate to get rid of the evidence.
