Was thinking about someone's post in another thread about the whole "state your name" business - they appeared to be DHS employee and said you'd be asked your name, but weren't required to say it, and something else about what being asked your name WASN'T for. But they never said what it WAS for. My take on it? Asking someone to state their name starts the "cooperation process" and makes it harder for the average Joe to then decide not to cooperate later on in the process.
Just my two cents.
