Sorry, I wasn't referring to an official cover up. What I was trying to say is that families tidy up when they find a body. It happens, for the reasons I said, officials, police and the rest are about to decent on their home, they don't want them to think they live in a pig sty.
Even if there was something drugs related laying about because it was chucked away doesn't make it a cover up. This is the real world, and things happen that in the cold light of day perhaps shouldn't, or were done for the wrong reasons. unfortunately in this real world, human error, when it concerns anyone who's in the public light MUST for dubious reasoning be some for of conspiracy.
