That's an alarmist exaggeration.  See for example
http://connectmedia.waag.org/toool/whatthebump.wmv
(warning: 97 minute video!)

This is the video of "Bumping Revisited", a conference presentation
earlier this year in which bumping is explained and demonstrated, and
then new countermeasures from lock manufacturers are shown and  
discussed.

Executive summary:  Security by obscurity serves to prolong bad design
which the bad guys likely already know how to break.  Open lockpicking
has already lead to new improved lock designs.

Share and enjoy,
