Sorry, repost
SELECT <whatever you want to select from a>
  FROM yourtable a
 WHERE EXISTS (SELECT 1 
                 FROM  yourtable b 
                WHERE a.birthdate < b.birthdate
                  AND <whatever criteria you use to identify the given officer >)

declare @dob datetime
set @dob ='12/12/1960'
select * from OFFICER where  Officer Date-of-Birth
>=@age
