VW Passat 35i easy to crack??

Hello, unfortunately I had to find out on Monday morning that my 93 Passat TD was broken up and the radio was stolen. Apparently NO violence was used. So no lock or the door destroyed. The Kripo meant the VW Passat would like to be broken up because this is especially easy and without violence. Now my question: Is this really true? Is the Pasat really so easy to open?? Or were there more professionals at work? I would be very happy about numerous experiences. Thank you. Merlin5001
