I don't think it's scary, but I also think it's not true.
I mean a lot of media equipment do pick up paranormal activity I.e orbs, sounds, visionary phenomenon and sometimes even interference.
However, you have to understand, MJ is a public figure how ironic is it that it should be on the news, filming his house there is room for fake phenomenon here, for publicity and whatnot.
Only some people posses the gift of seeing phenomena by their own eyes, some fortunately and some unfortunately (me in the latter) not everyone, unless such souls wanted people to see them or to be haunted.
Can you understand where i'm coming from?
