When a cop says, "You seem like a really good person." Here's what they're really doing. They're flattering the crap out of you so you'll talk to them so that you'll give evidence against yourself so that they'll be able to write in their report that you confess so that they can convict you of the crime that they're investigating. You see how all that just flowed right along because you didn't ask for a lawyer. Don't ever fall for this. At the end of the day, what the police officer really wants is for you to talk to him and he's going to engage in conversation with you that feels normal, that doesn't feel interrogative. But what he's really doing is he's building a case against you.
