Duplicates in Crime Inceident Data

[Pete Leasure]

Hello,

I am looking for the best way to identify duplicates in the crime incident data. dc_key seemed promising, but it is unique for all observations in the subset of data I am examining (DUIs). And a sort of observations on dispatch_date_time and location_block shows a large number of potential duplicates. 

Any thoughts?

Delete duplicates that have the same dispatch_date_time and location_block?

Best,

Pete
