I think something interesting to glean from the articles is when obstruction is allowed. Up until you are commanded to stay or "detained" you don't have to be searched, hand over property, etc. But keep in mind if your actions "could" be construed as suspicious. Things as simple as crossing in front of a store multiple times have initiated a Terry stop legally.
And a lot of times if you ask the LEO if you are being detained he will not answer the question. If you are detained they are sometimes reluctant to tell you why also. They will fabricate the RAS after they find something. MOST people won't bother going to the station afterwards to file a complaint. Plus you are likely to get a mark in the system if you do complain. It takes effort and determination to stand up for yourself. Like I said compliance is easy.
