I looked at the new "evidence".

1) The fact that 3 lads were (maybe) in Luton and London the 28 of June does not prove anything. Why not showing more 7/7 footage ?

2) Out of the 5 CCTV images from Luton 28 that appear on the BBC movie, there are two frame that cannot represent physical reality : 08 :10 :36 and 08 :10 :37 (See two pics above)

On each image, look at the two character on the right and try to explain how the bloke without a baseball cap can have his feet largely in front of the the bloke with a baseball cap and his torso largely behind. This is physically impossible.

Here is a link to download the BBC video : rtsp://rmv8.bbc.net.uk:554/news/media/avdb/news_web/video/9012da6800275c0/bb/09012da68002790d_16x9_bb.rm

You can't download with a browser as it doesn't support rtsp protocol but you can use Net Transport for doing so and that you can download here (last freeware version) :  http://www.321download.com/LastFreeware/page9.html#Net%20Transport

I have also resized and cropped the Luton pic of 7/7 and the 08:10:36 one of June 28 as to make make them exactly correspond. (See animated gif)

You can see that on the 7/7 pic the lad behind with the white baseball cap has the legs missing.

Cheers.
