Among the cases dismissed by the grand jury disposition, what percentage of cases is where the subject is injured?
dismissed by the grand jury disposition refers to grand_jury_disposition = 'No Bill'; the subject is injured refers to subject_statuses = 'injured'; percentage = divide(count(incidents where subject_statuses = 'injured'), count(incidents)) where grand_jury_disposition = 'No Bill' * 100%
SELECT CAST(SUM(subject_statuses = 'Injured') AS REAL) * 100 / COUNT(case_number) FROM incidents WHERE grand_jury_disposition = 'No Bill'
