I definitely see the law enforcement value in those tools.  But what I keep coming back to is what Gen Flynn's case has made us starkly aware of:  if dishonest people have access to the information, they can use it to railroad people.  If we could actually trust the FBI, that would be one thing.  But currently we can't.  I think the concept of a federal investigative agency is a good one.  But it's not been good i  2ee2  n practice going all the way back to J. Edgar Hoover and maybe before that.  That's the dilemma.
