I was re-watching the TNG episode Haven and it hit me that the telepathy of the Betazoids is completely dangerous and highly immoral. Lwaxana Troi seemed so willing to read people minds and blurb out secrets that it seems there should be a law to protect those who don't want there minds read or some equivalent to the data protection act.
What would happen if the the victim was unwilling to having his/her mind read and the Betazoid did it anyway either forcefully or more secretly? Could the victim have the Betazoid arrested or sue him/her because what the Betazoid had done is really just mind-rape.
What if the Betazoid did one further and used the information to black mail the victim, psychologically torture the victim with personal info like being raped as a kid, steal info from a top Starfleet officer or use the info ruin someones marriage etc?
