Article 40 still supports police surveillance at border points.

"but it was in spirit I thought a violation of Schengen"

there is no spirit of Schengen, it's another control system. Problem; it equates Greek data quality with German data quality, madness.

bilboburgler - it was not at a border by by Stuttgart that the Hitler youth (acted like it) rousted me - so it is common on domestic trains, at that time, to have brutish checks on trains inside Germany - I mean I was left with all my belongings in a pile on the floor of the baggage car about 3 am, with nothing illegal found.

Makes me wonder about German law that allows this!

Well I do guess Schengen is rather meaningless then.
