I've been through three academies. The first one was a comprehensive academy. I was told when I was at my first agency to forget everything I learned and do the way I was taught by the agency. The main reason is the area I worked took a long time to update their academy, while the agency changes quickly.
The second academy I attended was essentially law and legals and high liability. Since it wasn't as comprehensive I did have to forget anything from the academy. I had to forget old bad habits.
The third academy taught much more than I needed to know. Out of a 12 week six day a week course I have used two or three hours of the training and that training was on the operation of inspection equipment. The rest was forgotten quickly.
But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security.
Translation for the intellectually challenged: If the government screws the people too much, it is the right and duty of the people to revolt and form a new government.
