6.2.Tear gas canisters should never be fired directly at or against a person. 6.3. Tear gas or water cannons should be used only for dispersal and never to secure compliance. 6.4. Tear gas or water cannons must never be used where people (bystanders, participants, both violent and peaceful) cannot leave the scene due to geographic or infrastructural barriers. They should only be used if violence has reached such a level that targeting individuals engaged in violence is not a possible or sufficient response. 6.5. The aforementioned must be used only after a verbal warning, with adequate opportunity for the protesters to disperse. 7. Given the extensive harm that batons, tear gas, other chemical agents, and water cannons cause, those should only be applied following a decision taken at the highest level of command and by police officers who have received extensive prior training on their proper use. 8. Even in instances where a protest turns violent, law enforcement must ensure the rights of protesters are protected, such as the right to life and liberty upon arrest, detention, and torture. 9. All use of force by law enforcement officials must be documented promptly in a transparent report. Where an injury occurs, the report should contain sufficient information to establish whether the use of force was necessary and proportionate by setting down details of the incident, including the reasons for the use of force. 10. Law enforcement must not physically pursue protesters fleeing the protest site. 21
