I could be wrong but I dont see this as anything particularly unusual in high profile case like this with an on-going investigation. The cops probably dont want the media to follow them around as they issue search warrants and interview witnesses as they are putting their case together.
Sounds ‘bout right to me - and I LIKE conspiracy theory (as a hobby...).
