I was happy yesterday!! 
Hey don't worry, we all have our grumpy moments, some more than others, but we don't hold that against you.

Obviously inconsistencies from the police are simply that, very minor and have little impact on anything. Although inconsistencies in JB's evidence are likely to be manipulation of the truth designed to quite literally get away with murder.

I suspect that inconsistencies are part and parcel of any investigation, particularly one carried out so poorly during the initial stages.
