What Difficulties did Alcohol and pubs cause for policing?

Alcohol made more people vulnerable to becoming a victim of crime. For example, all of the Ripper's  victims were alcoholics and it was likely they were all drunk when attacked. Furthermore, there a many examples of victims being robbed whilst drunk

Alcohols turn to crime to get money for drink (perhaps after losing jobs)

Alcohol reduced people's inhibitions and affected judgement- leads to wrong choices and committing crimes. Also makes small disputes much worse and make work harder and more dangerous for policemen

Finally, it plays a part in violence and abuse in families
