To refuse the search was his blunder. Hope all ends up ok though.

In fact, under the circumstances, wearing an empty holster could almost be considered an invitation to a Terry frisk.
I understand what the student was trying to advocate, but he failed to recognize the realities under current law. The police were caught in a no win situation and made a conservative judgment call after extensive efforts to make their duty as painless as possible for the student.
As a general rule, if you are on shaky ground and push a point with the police, they're unlikely to just shrug their shoulders and walk away. They're in the business of resolving issues, and the likely end game in such a case is an arrest that throws the matter to the courts to sort out.
Prudent folks find ways to avoid letting things get to that point.
