In so doing, they also broke off the locks! It's a new time and age we're living in, so it's better to be safe than sorry. This also taught me a lesson: pack additional locks just in case...
We purchased TSA approved locks. That way they can open your bags but the locks are not broken. You can tell if they've opened the bags by the color on your lock.
The other suggestion is to use plastic wire ties to secure your bags. If they are cut, you know they've been opened.
