"It is also an offence under section 58 of the Terrorism Act 2000 to take a photograph of a kind likely to be useful to a person committing or preparing an act of terrorism, or possessing such a photograph. There is an identical defence of reasonable excuse. This offence (and possibly, but not necessarily the s.58A offence) covers only a photograph as described in s.2(3)(b) of the Terrorism Act 2006. As such, it must be of a kind likely to provide practical assistance to a person committing or preparing an act of terrorism. Whether the photograph in question is such is a matter for a jury, which is not required to look at the surrounding circumstances. The photograph must contain information of such a nature as to raise a reasonable suspicion that it was intended to be used to assist in the preparation or commission of an act of terrorism. It must call for an explanation. A photograph which is innocuous on its face will not fall foul of the provision if the prosecution adduces evidence that it was intended to be used for the purpose of committing or preparing a terrorist act. The defence may prove a reasonable excuse simply by showing that the photograph is possessed for a purpose other than to assist in the commission or preparation of an act of terrorism, even if the purpose of possession is otherwise unlawful."
