"Poverty, manslaughter and stealing apples: police records shed light on Dublin 100 years ago," journal.ie (2015-05-14) http://www.thejournal.ie/police-records-arrests-100-years-ago-dublin-2765946-May2016/

LIFE IN DUBLIN in the early 20th century was tough, especially given the huge class divide. However, it was also a time of remarkable change. Newly-released digitised Dublin Metropolitan Police records show us what life was like from 1905 to 1918. The records cover some of Dublin’s major historical events, including the 1913 Lockout, the 1916 Rising and its aftermath. Over 30,000 people were arrested during this period and these details are all contained in the records.
