This article is not about the institution as a greater whole. It's not about the bigger picture. It's about the Memphis PD. That's what's on the table here, and that's what the title should make clear.
Sensationalism is the concern, not criticism of police.
The article is about her experience with the local PD, yes. The context of the title relates to the here and now which is a data point in the greater picture of how the police in general behave. It's only sensationalism if you ignore everything else going on around us.
I think I understand what you're aiming at. I think I would agree with you if the title wasn't so rigid, but it feels to me like a significant claim that extends beyond the here and now reality.
