According to most official documents, any passport which has a faulty rfid will be assumed tampered with, and will become invalid. So unless you want to be refused entry and forced to replace your passport, this is unadvisable.
Do it on a busy travel day and suddenly the authorities have to deal with a ton of broken passports. Either they arrest everyone, or they let everyone through.
Of course, you probably couldn't get a suitcase-sized RFID zapper through security, but you could show up, set it off a few times, and then leave without arousing TOO much suspicion.
Or at the passport issuing office. Now that would be chaos.
That was in the days before RFID. My passport has a bar-code and every entrance station already has a reader, so RFID is redundant anyway.
