Hello j:

If they're doing their job, they'll find them.

Most PO's run your name into the NCIC computer at least once a month to "catch" any outstanding warrants. They also like to run your name when you are near termination of your probation as well so don't think you'll outsmart your PO by not telling them something they will certainly find out about with a few keystrokes. You'll only be kidding yourself and pissing off your PO in the process.

They are able to look up if you have any warrants. My boyfriend's PO sometimes would look up if he had any warrants when he went in to meet with her.
