I have seen more dead people than I care to remember, and this lady does not look dead to me, though I claim no pathology or coroners credentials.
She does however look completely broken psychologically and mentally exhausted. This is a look that I have seen on people in/post combat, so one wonders how what started as a traffic stop, which moved on to a discussion about the lethality of her cigarette that she was smoking in her own car turned into an arrestable offence...?
As has been discussed on countless threads, there does seem to be a problem with US cops escalating a situation, in which once a process has begun there is no room for discretion or common sense. Handcuffs, beating, tazing, pepper-spraying and a seemingly equitable custody process, by which I mean equitably horrific - traffic violators are treated the same as serial killers and rapists.
But back to the point, I doubt she is dead in this photo, and appalled that the legitimate questions surrounding her death is diluted amongst nonsense claims such as this.
