Had to double check. The article says "domestic" suspects so I suppose that means citizens. Here is a case where I am in favor of big government not having this power.
In reality I have not been arrested THAT MANY times I know how long it takes to get mirandized and get in the lawyer request on average. Suppose this will extend it three hours at the least.
The Miranda rule du jour (it changes from month to month) is that if a suspect is under arrest, or the "functional equivalent of an arrest," he must be Mirandized prior to questioning. There are several exceptions to this which usually do not apply, so I won't go into them here.
Being placed in the back seat of a police car, being handcuffed, being told to sit on the curb, prior to actually being placed under arrest, are considered to be the functional equivalent of an arrest.
