You can never 'investigate' something where the truth is already known in advance, it's accepting the truth in the first place that is the barrier, and once enlightened there is no need for investigation because those who are culpable will carry out the investigation and NO guilt will ever be apportioned EVER!
Remember you are in the minority, and the majority will try to force their views and opinions on you.
Just be satisfied you didn't submit and have retained your health.
