"In the 1930s, British football crowds were as orderly as church congregations. Today our soccer fans are a byword for aggressive violence. In the first-class matches in 1946-47 only 10 players were sent off. By the mid-'90s the total number of red cards issued in a season had reached 451. Hooliganism is not confined to our footballers and their supporters. In 2002, a survey by the travel company Expedia of tourist offices in 17 countries found that, for loutishness, British visitors were top of the league.
At home the yobbism of the football crowds is only magnified in the incidence of violent crime, which rose from 4,221 in 1898 to 331,843 in 1998-99. Even adjusting for population growth, that amounts to a 47-fold increase. The situation is actually worse than the numbers suggest, for the laws and their enforcement were stricter a century ago. Indeed, as one eminent authority, Professor Jose Harris, put it, "If Edwardian standards were applied in the '90s, most of the youth of Britain would be in gaol."
"In 1912-13, for example, one quarter of males aged 16 to 21 who were imprisoned in the metropolitan area of London were serving seven-day sentences for offences which included drunkenness, 'playing games in the street; riding a bicycle without lights, gaming, obscene language, and sleeping rough."

The level of acceptable disorder in modern Britain is so high, it is ludicrous.
I haven't been subject to many crimes, but have attempted to report financial fraud of various kinds - police not interested; arson - not interested; minor assault - not interested; large-scale importing of counterfeit goods - not interested.
I am sure there are many other examples - from the police in the 1930s having the time to prosecute people for swearing, you'd now be lucky to see them for anything short of GBH.
