One of the reasons illegal drugs are as dangerous as they are is because they are illegal. Their illicit nature means they are manufactured and distributed without any proper oversight or regulation, leading to dangerous lack of quality control.
If recreational drugs could be purchased with proper standards for purity, dosage etc they would be much safer for their users.
Why is it even possible to turn off or delete footage from these cameras? I would have thought they would be treated like black box recorders - always on, always recording, and only reviewed when absolutely necessary.
This is like a failure of both technology and policing culture.
