People make mistakes. Ordinarily those mistakes are discovered and corrected, the person who made the mistake learns from their mistake and is wiser for the entire experience. This is how the world is supposed to work. However, sometimes people don't learn from their mistakes or they still continue with a course of conduct even knowing their conduct is risky. Whether it be texting and driving or failing to do routine maintenance on a semi-truck, continuing to conduct risky behaviors eventually causes harm. Sometimes the harm befalls the person conducting the risky behavior but more often the harm is shouldered by an innocent person. When an innocent person is killed due to the willful risky behavior of another it generally sets off a chain reaction or finger pointing and deliberate obstruction of the truth. Unfortunately, the type of person responsible for conducting willful risky behavior is generally the type of person who is willing to take a big step back when that risky behavior harms another. The type of person who is willing to put others at risk is very likely to try and hide or diminish their role when their activity harms another.
