load_all_police_outcomes.RdLoads all the police outcomes data available, tidies and cleans the data set, and calculates rolling sums for the relevant groups.
load_all_police_outcomes()
Returns police_outcomes open data for a given financial year. Data is
tidied using tidy_police_outcomes before being cleaned
and turned into a rolling sum.
Currently this implementation doesn't detect the files in the bucket and so if poorly generalisable. This should be fixed. Ask Xennor.
