As per Wikipedia "the Metropolitan Archdiocese of Baltimore is the premier (or first) see of the Roman Catholic Church in the United States". Even today the homicide rate in Ireland is a fraction of that in the USA let alone Baltimore BUT in 2006 the Sunday Tribune published an article that proclaimed that the previous year had seen the highest number of homicides in the history of the Irish State -at least since the aftermath of the Civil War in the early 1920s. This was the middle of the Celtic Tiger era; were poverty and oppression to blame? Well actually a high proportion of Irish homicides were/are related to drugs and gang warfare so there IS a certain similarity to the chaos in Baltimore even if the death toll is a lot lower here.
Denouncing "oppression" or "racism" doesn't get us very far in trying to analyse the causes of crime and drug addiction either in Ireland or the USA.
