This was forwarded to me for info -

I wanted to drop you a note about photography on (or even near)
LUL property. Earlier today I took a photograph of the front of
Pinner station, and the footbridge. Two BTP officers who had seen
this promptly detained me under section 44(2) of the Terrorism
Act 2000 (http://www.opsi.gov.uk/Acts/acts2000/00011--f.htm#44),
and informed that photographing anything that the Government
deems 'critical national infrastructure' (which includes the
Underground) is prohibited unless written permission from the
property owner can be produced.

There is nothing in this part of the Act which prohibits photography,
nor is "critical national infrastructure" mentioned. The Act does,
however, give the police very wide powers of stop and search provided
that the necessary authorisations are made and renewed every 28 days.
Note though, that this power "may be exercised only for the purpose of
searching for articles of a kind which could be used in connection with
terrorism", not apparently for prohibiting photography.

I'm always a bit suspicious of forwarded mails like this. Have you seen
the full original mail? On what date was it sent?
