At the end of The Invisible Man (2020),
Adrian seemingly kills himself by cutting his own throat and this activity is recorded on CCTV. However, we all know it was actually Cecilia using an Invisibility suit.
The movie implies she'll get away with it because there is supposedly incontrovertible evidence that he did it to himself.
But by this point, don't the police know that Invisibility suits exist? I mean she is certainly using it for her own defense which is corroborated by many witnesses at the hospital, the (albeit broken) suit found at James' house, and the raid by the SWAT guys of Adrian's house seems to suggest that she is believed by the authorities.
So why won't the police, when looking at a man looking all smug and satisfied suddenly decide to take a knife and kill himself (possibly looking surprised while he's doing it!) not wonder if it was really someone in an invisibility suit? I'm sure Cecilia leaving the scene after calling 911 will only make them more suspicious.
(I know we never get to see whether they do, but the movie ends implying that she's getting away with it).
