When a country really wants to get you, there aren't many safe places in the world. The terrorist Carlos got abducted by the French intelligence service. Eichmann by the Israeli services. There are less famous cases (like the Kalinka Bamberski case). What's interesting in that in all of those cases, these illegal means of grabbing the suspect abroad didn't invalidate the case against him and in all of those examples the suspect was then charged and sentenced.
So yeah maybe, but only for some petty crimes.
