I am not trans and I have no experience with this sort of thing, however femboy might be a safe transitionary identity for you. That is of course, assuming you are comfortable with the label.
However, this is just an observation from an outsider. I am sure someone more qualified will have a betyder answer than me
What a horrible thing to happen. Was hear use of "rebuke" odd? Sure, but hardly threatening. I am very curious what the officer has to say in his defence, I do not see hos this could anything other than murder. Perhaps discussion of which degree, but surely murder and not manslaughter.
I am devastated on behalf of Massey's family and I hope they will eventually find peace.
