7 7 bombings and the killing of Jean Charles de Menezis

So I was convinced that this happened on the day of the attacks.

I have a clear memory of the news report about the cops shooting him at the underground station on the day of the attacks.

Now though I am seeeing this "The series will be produced by Bafta-winner Jeff Pope and examines the story of the Brazilian killed by police weeks after the horrific events having been mistaken for a suspect."
And from Wiki
Born Jean Charles da Silva e de Menezes
7 January 1978
Gonzaga, Minas Gerais, Brazil
Died 22 July 2005 (aged 27)
Stockwell, London, England

Any idea what is happening here?
Am I losing it?
Is it a Mandela effect?
Something else?

Its ok, sorted it out it was the subsequent bombing on the 21st that he got shot at, both things joined up in my mind
