My question involves police conduct in the State of Massachusetts.
I am trying to learn about my rights during police-citizen encounters. I understand this is a lot, s please answer as much as you can briefly.
1) What (generally) are the types of police-citizen encounters and what information / documentation am I legally obligated to provide during each type of encounter?
2) If I assert my right to remain silent, assert my right to counsel, and ask "am I free to go":
A) Does this always stop questioning?
B) How long can I be held during each type of encounter?
C) Can the presentation of anxiety or panic in myself be used to continue to hold me or continue questioning after I have asserted my rights?
3) Are there any situations where my right to remain silent and my right to counsel will not be upheld during a police encounter (such as at a highway checkpoint or if I am approached by an officer as a witness to a crime)? Under the law, can asserting my rights in these situations make me look suspicious?
4) If I want to refute / appeal a vehicle moving violation, is there anything I should do or say during the traffic stop encounter with the officer?
5) Am I ever obligated to allow a police officer to search myself, my vehicle, or my home without a warrant?
6) What types of stress inducing psychological tactics are the police allowed to engage in and where is the line that they cannot cross?
