They are also taught that the Lateral Vascular Neck Restraint (LVNR) is the safest way to restraint someone. The truth is, that it is not. It is stupid to believe that cutting blood supply to someone's brain is safe. LVNR is a scam that nobody actually believes in but everyone is silent about it because it is a plausible excuse to kill people.

No death, injury or litigation? Bullshit. It only resulted in 1 month of protests and billions of dollars lost.
