"which" after a dash [closed]

Solution 1:

From a purely syntactic perspective, the wording is ambiguous. "Which" here could apply to either "discriminatory enforcement" or "ending discriminatory enforcement".

Given that the article gives no indication that discriminatory enforcement has ended "around the county", it likely was meant to apply only to "discriminatory enforcement". Indeed, if the author believed that discriminatory enforcement had ended around the country, it seems unlikely that the article would have been written at all.
