To recap: Lena Dunham lied about having information which would disprove Aurora Perrineau's allegations of sexual assault against Murray Miller. Perrineau was r/ped by Miller while she was a part of Dunham's show, Girls.
"I'm sorry for my actions"
"What I did/said was wrong"
It should express that you understand the impact of your words/actions, and it should seek to make up for them.
At the very least, she should privately offer to cover any expenses Perrineau may have had to make for therapy as well as part of her legal fees.
