The US Supreme Court has found that a cop -- even ON DUTY -- can't be sued for failing to act, even if a death results from that inaction. They aren't there to protect individuals.
This is why it's the utmost in hypocrisy for the government to deny you the right to defend yourself when they refuse to.
The supreme court is often wrong, that's why decisions are often reversed.
If I recall correctly the Supreme Court decision was that cops don't always have to respond. In other words by by default police should normally be held accountable for their actions, and should be subject to being sued for failing to do their job.
There are some circumstances where police should be immune to lawsuits. Such as if they are overwhelmed. Like if there is a disaster, they would have to ration and prioritize their response. However there are many circumstances that I think does not fall under the Supreme Court's ruling, if it does it shouldn't. If cops are too lazy or prejudice to respond to a significant crime and if there isn't a justified reason, then they shouldn't have immunity. Law enforcement and our government has a duty to protect and serve, if they don't then they should be prosecuted for dereliction, and should be held liable. Under the Constitution, we are supposed to have equal protection under the law. When police officers and other government officials use our prejudice with providing protection and services; they are violating the Constitution. They should be prosecuted accordingly.
The vast majority of police that hide behind that Supreme Court ruling, should be fired, prosecuted and barred from public service. Every time I've personally heard a cop used that Supreme Court ruling; they were corrupt, derelict and incompetent.
Part of the reason that law enforcement has such a bad reputation. It is because they are so corrupt and so derelict. They often claim they care about the law, justice and public safety; but very often their actions prove otherwise.
How do you think the public feels, when police say they are too busy to do their job when there is egregious crime or a significant threat to public safety? Police goof off so much, that they have a reputation for goofing off at the donut shop. Policies have shifted the goofing off away from the donut shops, but never less than goofing off continues. I often see police loitering shooting the breeze about who got beded, ballgames results etc. yet when there is menacings, assaults, drunken driving, drug abuse, drug dealing, etc. law enforcement often claims they are too busy to file report or do an investigation. Sometimes they even harass, slander and threaten to arrest the person trying to file a complaint.
In part our government doesn't have any credibility because they don't properly vet themselves. They don't do their duty and they don't abide by the law.
This is why it's the utmost in hypocrisy for the government to deny you the right to defend yourself when they refuse to.
Our founding fathers had the foresight to know that there inherently is an element of corruption, incompetence and dereliction in law enforcement. Our founding fathers knew that even if law enforcement is honest and doing its best; that they can't be everywhere all the time.
That's one of many reasons why our founding fathers put the right to bear arms in the Constitution. We can't depend on law enforcement and other agencies in our government.
. Never knew that.
