Except this comes in in real life all the time: "you don't need a lawyer here, you're not guilty..." - yes you do. You always need a lawyer. You always should plead the 5th if it applies. No, you should never be talking to law enforcement without a lawyer. No you should not let law enforcement "take a look around" without a warrant.
Real life is full of things you absolutely should do which are sold up and down through media as "looking guilty".
