The fact that you've tried to get the police involved speaks volumes about you. What did you expect to be the outcome of that? Surely you didn't tell them you were being harassed by a secret society because you frequent conspiracy forums?
Anyone who would expect that to make any difference with a cop must have a screw loose.
Doesn't mean they aren't out to get you, but I'd have to wonder why they'd target you when David Icke has only just been targetted by them...after writing several books.
I would suggest you are doing this to yourself OR are secretly more important and dangerous than you realise. I'd gamble my money on the former not the latter.
