The fundamental problem is that socialist statist (otherwise known as communism) brainwashing throughout the 20th century has taught people to see the government and it’s officials as beneficent servants of the people acting in everyone’s best interests. Therefore, jurors do not want to “interfere” with the police who are acting in everyone’s best interest by protecting them from “bad people” like Mr. Kelly. So, it becomes easier to excuse the police when they are simply “overzealous” in protecting us.
Naturally, these jurors would not want to be responsible themselves for dealing with Mr. Kelly. These same people see the police as being responsible for their personal safety; so, they want the police out there protecting them no matter how the police accomplish that protection.
These people would be horrified to discover that the police have no legal responsibility to keep any individual safe. They do not realize that the reason that the police have no legal mandate to protect them is that the law correctly places the responsibility for protecting individuals on the individual, not the government or it’s agents.
As a result of socialist brainwashing, many people are too willing to trade their liberty for a false sense of security provided by the government which is what Ben Franklin warned us against. Libertarian thought which correctly emphasizes individual liberty in conjunction with individual responsibility is the best defense against that brainwashing.
