Case in point:
Short version for those who don't want to visit the link and haven't
followed the story: People asked Symantec for server certificates of
domains they didn't actually own, and they were given them. Mozilla and
Google were not amused.
There are other stories as well, but that's a good illustration of
why it's a bad idea to just hand over a bunch of CA's to users without
any mechanism for keeping the CA database, and CRL's, up to date.
Mozilla and Google like to update their browsers every few hours,
which is annoying, but at least it helps keep the PKI datastore up to date.
