No not necessarily.  My understanding was that if you required assistance from above, you would have to tell them "listen I've got big problems, I need help", but if that senior officer couldn't do anything for you in any case you didn't inform him, otherwise you would give him knowledge which could create problems for him later.  In this case there was no necessity to inform anybody else, because the scene was solved by the members who were present at that scene and it wasn't necessary to obtain sanction from anybody else because I think it depended from case to case.  In the other cases they may have required assistance from above to cover up an incident and that is why they handled the matter as such.
