Apparently, maybe not always, but sometimes, when there is smoke there is a significant probability that there is fire also.
This seems to be the case in Arizona where the well known but smokey Sheriff of Maricopa County, Joe Arpaio, seems to have run a department in an area of the country known for its significant Hispanic population, not to mention close to the border of Mexico, that
unfairly [targeted] Latinos for detentions and arrests and [retaliated] against those who complain.
