Documents obtained by the Guardian reveal that last summer's riots in England provided a major impetus to Home Office research into new-generation riot control technology, ranging from the Dip to even more curious weaponry described by Cast technicians as "skunk oil".
The briefing by Cast for the Police Service of Northern Ireland says that last year's disorder sparked a surge of ideas to the Home Office from the public as well as companies manufacturing police technology. To capitalise on the interest, Cast convened a "brainstorming" event in October. Participants included police from London and Northern Ireland, the Police Federation, the Serious Organised Crime Agency (Soca) and the Ministry of Defence's Defence Science and Technology Laboratory.
"No ideas too stupid or 'off the wall' to consider," the briefing notes record.
The November briefing, The Development of New Less Lethal Technologies, suggests that the Dips would be loaded into guns used to fire the existing generation of plastic bullets. They would be intended to be accurate at a range of up to 65 metres.
