So you believe the justice system didn't deliver justice and Chauvin received the wrong sentence? If that's the case, we clearly can't trust the justice system, so my question on how we determine whether the State is issuing violence or force is the same. By locking up Chauvin unjustly, has the State used force, or violence?
