Details

The medical assessment was undertaken by the independent Scientific Advisory Committee on the Medical Implications of Less Lethal Weapons (SACMILL) which reported to the Home Secretary on the likelihood and impact of the risk of injury from the use of water cannon.

To inform this assessment, each of the water cannon purchased by the Metropolitan Police has been tested by the Home Office Centre for Applied Science and Technology (CAST).

Redactions

The Home Office’s rationale is to be as transparent as possible in providing the background documents that informed the Home Secretary’s decision. However some sensitive information has been redacted to protect personal details and commercial interests and to avoid prejudicing the ability of the police to enforce the law. As a general principle, information has been redacted where it would be exempt from disclosure under the Freedom of Information Act, should a request for it be received.
