This guy and most terrorist do not probe.
They are either recon|setting up, testing or they are doing.
Probing is some half cocked nonsense we've made up.
There are a variety of medical treatments and examination methodologies that can and do take place in the rectum which involve the use of magnets.
In many cases a failing sphincter muscle's performance can be improved with a couple of magnets attached to a two-wire circuit. After you are "done" you plug the lead wire into a battery pack, or throw a switch (depending on how sophisticated the device is), and the magnets make sure the sphincter closes.
I think some of the characters referring to "probes" know all about this. We might collect their names and do a follow up survey and then publish a set of personal testimonials right here in FR.
Bet we'd hear some magnets clicking on that.
