Again, you can be "not free to leave" for a whole hour on the side of the street and have a judge call that a "reasonable" period to detain you for questioning. You're not under arrest while that's occurring. A bunch of other processes get set in motion once you're arrested, all of them bad.

Probably don't overreact if you hear a cop say "stop, get back over here!" or "no, you may not leave until I get to the bottom of this!"; they're legally authorized to do that pretty much on a whim.

If you've been handcuffed or transported or confined in a police station, you're under arrest, and yes, demand a lawyer.
