I don't think status has anything to do with their comment. What made you bring it up?
To label a group of people lower than the lowest implies these people belong to a lower class.
class = status
You're going to have to be a lot more specific. What makes you think 'bottom of the barrel' was referring to the social status of the woman?
The obvious implication is that drug dealers are low-status individuals who deserve this kind of treatment.
Black people are the most consistently anti-police demographic so I don't know where you're getting the idea that it's "young western kids" that are propagating the anti-police rhetoric.
