Arsonists attacking commercial properties with links to people’s homes could be shot by police during future riots, an official review of police tactics has recommended.
The use of firearms could be justified given the ”immediacy of the risk and the gravity of the consequences”, legal advice published in the review said.
Plastic bullets and water cannon could also be used by officers facing riots similar to those seen this summer, the review by Her Majesty’s Inspectorate of Constabulary (HMIC) added.
Police need to be better prepared, trained and ready to protect the public if they are to improve their response to similar scenes of violence and looting in the future, the review found.
