Sean Hoare, it appears, was in fear for his life from some unspecified Government agency.
See Police say 'no-one else involved' in death of phone-hacking whistleblower who 'feared someone was out to get him'.
According to a neighbour, "He would talk about someone from the Government coming to get him".
Were those fears the unfounded paranoia of someone known to have had alcohol and drug problems?
Or could those fears have been well-founded?
Just because you're paranoid it doesn't mean they're not out to get you.
