He claims the release of information facilitates terrorism, without sharing any argumentation: no examples, not even hypothetical scenarios, nothing.

He's asking to restrict the sharing of information, supposedly information on how "the government fights terrorism". He glosses over the fact that once law enforcement can persecute people for sharing some information, it is incredibly easy to persecute people for the sharing of _any_ information if it choses to. Power creep is a scary and dangerous thing, and it is very hard (impossible?) to guard against it.
