FBI, ATF and officers from all departments can and do conduct probation compliance checks. It’s not unusual.
Really?
I’ve never ever seen anyone home or employment verification done by anyone but a US Probation Service officer
And I’ve seen...a lot.
I think there is more to this than some routine check.
Typically PO visit in beginning.
If you are good and work.....they know instinctively
You may never see them again except when you visit their office monthly or quarterly
