The agency statistics also show that more than 80% of those written up or warned since the fall of 2014 were people of color. That included 33 patrons records identified as black and 12 identified as Hispanic or other. A total of nine white patrons, or about 16% of the total, were cited or warned.
Li said she was "very concerned" by one media account of the data.
She said the purpose of the staff presentation early next year would be "to provide a data driven account for the way BART resources, particularly law enforcement, are deployed and the benefits to our ridership and system safety."
Contra Costa County board member Debora Allen pointed out that questions have been raised about the eating/drinking citation statistics, issued pursuant to California Public Records Act request by The Guardian.
"The number of violations that came out of the PRA was actually found to be incorrect," Allen said.
Officials with BART's police union have said that many of the citations that list Penal Code Section 640(b)(1) — the ban on eating and drinking — represent cases in which a patron was incidentally cited after being contacted by officers for some other offense.
For instance, the list of eating/drinking cases released by BART shows a "citation/arrest" last Aug. 21 at San Francisco's 24th Street Station. That incident, also reported on the BART Police Department daily arrest update, involved a 19-year-old Latino man who police took into custody for alleged battery.
The 640(b)(1) statistics are the latest numbers to call attention to the apparent disparity between the racial makeup of BART's ridership and BART police enforcement activities.
Based on its 2018 customer satisfaction survey, the agency estimates whites make up 35% of ridership, Hispanics 17% and blacks 10%.
But an October report on BART police use of force in 2018 said 59.5% of such incidents involved black subjects compared to 15.8% involving whites. In BART police parlance, use of force techniques range from grabbing subjects and using control holds to employing a baton, Taser or firearm.
BART's independent police auditor is in the midst of a review of all use of force cases for 2018 and 2019.
