Alessandro Pereira: 'Why did Ian Blair say my cousin was a terrorist?'

"Jean Charles de Menezes was aged 27.

He was a young Brazilian who came to London full of dreams and hopes. He loved London. He loved its vibrancy, he loved the fact it was home to so many different people from around the world. He was so happy to call it his home.

I want the people of London to remember that he was just like them. He was going to work on the Tube, like millions of us do every day. Except that, on 22 July, as he went to work he was murdered. He sat on the Tube, an innocent man, when his arms were held and 11 shots were fired. Seven into his head and one into his shoulder. The people who killed him were police officers.

I want the people of London to imagine hearing your son, your brother or your father had been killed on the Tube. Shot dead. I then want you to think how we felt when we were told he was a suspected terrorist. That he looked like a suicide bomber. That he was wearing a big jacket. That he ran from police.

I want Ian Blair to think how it felt having to ring Jean's mother and father, our family in Brazil and tell them their son was dead. That he was killed in such a way. We had to answer my family's questions about how and why he died. I want Ian Blair to imagine how we felt having to listen to the lies about Jean. About why he died. To see Ian Blair on TV telling those lies.

The police knew Jean was innocent. Yet they let my family suffer. They let us suffer. Ian Blair let us suffer. For three weeks we have had to listen to lie after lie about Jean and how he was killed.

The police even went to Brazil. They met my family. They still didn't tell us the truth. Did they think because we are poor Brazilians we do not deserve the truth? If that was Ian Blair's son would he not want the truth? He now says he didn't know. If he didn't know, why didn't he know? Why did he tell the world my cousin was a terrorist? Why did he lie to us?

We want to know why for six days there was no independent investigation. If there was nothing to hide. Why did Ian Blair stop the investigation? We want to know what evidence has been lost or damaged. What has he tried to hide?

If there was nothing to hide, why did the police tell my family not to have a second post-mortem? Why did they lie in their own post-mortem report?

I have always believed those who break the law should be punished. Some people have broken the law. They have killed Jean and told lies. They must face justice.

For the sake of my family, for the people of London. In Jean's name, I say those responsible should resign. Ian Blair should resign."
