If you want to know for sure that violent crime is far worse today than it was in the 1950s then go out and ask young people themselves! Then go out and ask pensioners about how bad violent crime was in their youth! And ask questions like: "Were their post code wars even a few decades ago?" And "How many people do you know who have been stabbed, shot, or killed?" And a good place to start doing research would be somewhere like Brixton.If you are so certain, you'll answer this rather than post youtube clips, or consider leaving it out
