4)If arrested don't say a thing- they will have to read your rights to you and part of what they are reading to you warns you not to say anything or you will get in more trouble, the other part says you can demand an attorney right then. Still yet, 84% of people know this and waive their rights anyway. And the police interrogation techniques are suprisingly powerful enough to get just about all these people into more trouble- even cops. Always say you don't want to talk to them and want an attorney!!!
