domestic violence refers to domestic = 'TRUE'; report number refers to report_no; in the bank refers to location_description = 'BANK'; percentage = divide(count(report_no where domestic = 'TRUE'), count(report_no)) * 100%
SELECT CAST(COUNT(CASE WHEN T1.domestic = 'TRUE' THEN T1.report_no END) AS REAL) * 100 / COUNT(T1.report_no), COUNT(CASE WHEN T1.domestic = 'TRUE' AND T1.location_description = 'BANK' THEN T1.report_no END) AS "number" FROM Crime AS T1 INNER JOIN Ward AS T2 ON T2.ward_no = T1.ward_no WHERE T2.alderman_first_name = 'Christopher' AND T2.alderman_last_name = 'Taliaferro'
