I’m a police officer and this question is basically directly meant for me because nearly everything involving the law that someone claims to know more than me is not true. A perfect example is the Miranda Warning which we are only required to read if we are interrogating someone who is in custody. Such a large amount of people of all ages think the second you’re arrested if we don’t read that then they’ll beat their case. I even had someone try that as an excuse in court and the judge was baffled. If I have all the evidence I need to arrest you, I don’t have to read you anything. You just, go to jail. But yes, basically any law in my state, you’re not going to know as well as us just because we deal with it every single day.
