Oh, you are worried about typing because it may lead you to have to  
make decisions about which authority to trust. That is a problem of  
database consistency not of typing. If two people say something  
different about someone, such as

:p rdf:type x:thief.

and another says

:p rdf:type x:honest.

You will need to decide what you should add to your database. And  
there will always be many ways you can render your database  
consistent. You can either reject one or the other proposals, or  
reject the proposal that a man cannot be both honest and a thief.

This is not a problem with typing. Its a problem about which  
statements you decide to accept and how you decide to keep your  
database consistent. The semantic web leaves that open for you to  
decide. You will have this problem by the way whether you have typing  
or not. As long as you have statements that can be contradictory -  
and unless you have those you won't be able to say anything  
interesting - this problem will appear.
