Not at the same time. Much of the racist aspect of US sheriff behavior is not shared with Europe, for example. Sessions was referring to the 250 year heritage of law enforcement by the sheriffs in the US. That's not a reference to the origins, but to the past and continuing nature. And to someone else, and about something else - such as habeas corpus, or the US legal system, instead of sheriffs. That's because it would have meant something else.
