Rachel from North London has been setting the scene for coming media coverage of new information on what was known and done about the London 7/7 attacks, both before and after. She is also calling on readers to sign the Downing Street petition for a public enquiry into the events.

“And then I started to follow a trail. I read, I researched, I found out more and more and more. I talked to people. I listened. I made it my business to know, as much as I could find out. Why? I didn’t want to let anyone down, by not being as briefed as I could be.

But what I found out was devastating. First, whispers, rumours. Then, facts, and I checked, and followed up, and I sat with what I knew, and sometimes I cried. And I bit my lip and waited…

It was, and is, not just about a failure of intelligence, but a failure to use intelligence. A failure of imagination. A misguided belief in a ‘Covenant of Security’, that was never security; that was a lie.

And for me, it is about the screaming I hear, still, in the darkness, when I sleep.

That might have been avoided, knowing what I know, what they knew, what we will all know, soon. And so I wait, and I write, and I wish, for what is coming soon…”

This is of course not the first attempt to build public and political momentum for an enquiry. However, it sounds as if April will probably see a new chapter in our understanding of what happened and why.
