The only solution I can think of is for Frontex to take full control of the external EU border. The way I see it, Frontex officers guarding the border would answer directly to Frontex (NOT to some national authority), would be paid by Frontex and, in case of misbehavior, would be prosecuted by an EU prosecutor.

This approach would greatly reduce the smuggling of illegal immigrants (which, in my opinion, happens because many Southern and - especially - Eastern national borders are porous due to easily bribable border guards). Sadly, I don’t see this happening anytime soon.
