How many young people are murdered on the streets of the US everyday? Why don't many other countries have...?

this problem? NYC has improved their situation, which other cities have? And, why isn't the general public phased by this information and statistics? I get the impression that the underlying sentiment of the average American is, "as long as it doesn't affect me or people I know directly, why should I care? I don't have to go into those areas". Do you feel this is a correct observation of how the average American feels about homicide in their own country?
