As you say, Schengen does not allow for large-scale border controls in Europe. Random checks are allowed though if they have the purpose of stopping illegal activity such as drug or money trafficking (e.g. from Luxembourg, the Netherlands or Switzerland).

The stricter controls that have been in place for the last weeks, which also only involve randomized searches on a slightly larger scale but only at several points of the border, are also legally covered under the Schengen accord and serve the purpose to get a better handle on the thousands of unregistered immigrants flowing into Germany every day (this year alone, more than 1.5 million regugees might come to Germany, many of them completely unregistered). Concerning the scale of the current crisis I think these measures are absolutely appropriate and not overly extreme.

I don't think this had anything to do with refugees. They busted the OP because they assumed they'd find drugs on him.

Young man - check. From Amsterdam - check. Dutch passport - check. Dark skin - check. Dreadlocks - check

In their mind this kid was going to have dope on him no matter what.
