French Senate proposes chemical markers to tag protest suspects

A French Senate mission on public order issued a 30-recommendation report that includes coded chemical-marking devices for police. The markers apply a coded liquid to skin and clothing from roughly 5–7 meters to link a person to a specific operation later. No procurement, deployment date or admissibility standard has been set.

• Senate report lists 30 recommendations on maintaining public order
• Marker is applied from about 5–7 meters and tied to an operation code
• A positive result shows contact with the liquid, not a crime
• No procurement decision, deployment date or court standard exists
