I dont really believe the cop was that nieve. This TS person has not transitioned if they are using the sisters identity. Therefore hard to have me believe that the person passes so well that cops interviewing them for even 10 minutes at the station could not figure it out? Now it could be, but has me curious about this.
The sister could be someone that is very non supportive and could be in denial of things her sibling has gone through. Lets face it families are not unknown for doing some damage.
And as well we do have to consider that this individual has some serious issues and needs help. It will be interesting to hear what the "investigation" uncovers if they even bother to really investigate anything. This would be so easy for them to get away with dismissing. You gotta admit the sister does not even want her name mentioned...so can we here family issues???
Peace
