I must say that some of you do us all a disservice with some of your replies. It is one thing to make criticisms of published or broadcast stories or documentaries but to lash out at a polite request for help before knowing the credentials of the poster is akin to exactly the same actions by some of the gutter media many of you so love to hate.
To accuse the poster of not researching something that is very technical and at the same time fail to notice that she states that she is making a documentary and not publishing a newspaper article is blatant hypocracy. A few of you have made polite and sensible replies but I sense a mass hysteria by some who only exhibit their 'bravery' when posting on here whilst cowering behind their protctive cloaks of anonimity.
Can we please have a bit of decorum on here? If you are rabidly anti-press then by all means make your views known but at least try and make sure you are not being hypocritical whilst doing so.
