I have now had a reply. It looks like a stock reply to me and completely failed to answer the concerns raised.
Dear Mr K
Thank you for your recent correspondence regarding photography in public
places. This EDM has now 'fallen' with the end of the last
Parliamentary session and so it would not be possible for me to sign
them regardless of my opinion. I appreciate your drawing my attention to
this issue. Photography is enjoyed by many people and it is important
that people are aware of their rights. Apart from in exceptional
circumstances, it is not an offence to take photographs in public places
and people should not be prevented from doing so.
When there are serious concerns about national security, such as at
military airports and power stations, there are necessary provisions for
photography being restricted. In general, however, Government buildings
are not covered. Indeed, the Houses of Parliament must be one of the
most photographed buildings in the world. Whilst the Metropolitan Police
recently launched an anti-terrorism campaign which encourages the
public to report any suspicious behaviour, including photographing
sensitive buildings, I am not aware that this specifically has led to
any harassment of photographers.
Once again, thank you for taking the time to write to me
Yours sincerley
James Duddridge MP
Member for Rochford and Southend East
