Think the following question over yourself. Don’t bother answering it here.
As the enforcer of the law, how many times have you casually broken the law and felt ok doing it? How many times have you seen a fellow police officer break the law and failed to hold them accountable or even helped them cover it up? In your experience, these events may have only involved minor crimes - not murder or rape or anything - but you almost certainly still operated in an environment of willingness to break the law and fraternal duty to protect your colleagues at any cost. The same situation is too common with serious crimes, as we see in the news on a regular basis.
Good cops don’t help cover up the crimes of bad cops.
Not too far from the truth. The scientists are also putting random stuff in there just to see what it looks like!
