>> From a few of your statements you are clearly confused on the concept of detention. Small town or not, exercising "influence" calls for a position based on proper authority. <<
A person is considered under arrest whenever they feel they aren't free to leave or are transported from the immediate vicinity (e.g., a police officer can not drive you arround for 30 minutes against your will). Laws governing detainment can not superceed Miranda. There are different statutes regarding detaining suspected shoplifters/thieves on premises, citizens arrests, private investigators, and material witnesses, (and vary state to state) but do not apply to this discussion. The discussion here is whether or not a police officer can detain someone against their will and interview them without Mirandizing them. The answer is "NO" and thats not television.
>>Miranda rights also are not a key element to an arrest as the TV shows seem to think. You can be arrested and never Mirandized. <<
I never said it was. Freedom to leave IS a key aspect of arrest and can define an arrest (e.g., a police officer can not hold you for 45 minutes as you keep stating you want to leave and later say he didn't arrest you. You were arrested but a judge will ultimately rule on that.
And yup, you can be arrested and never Mirandized but most if not everything you say after the arrest (even if the police officers try to call it a "detainment") is going to be thrown out. Miranda rights, whether stated or not, have to be respected.
