CAMDEN, New Jersey (WPVI) -- Five years ago it earned the reputation as one of the most dangerous cities in America. Now, Camden has its lowest crime rate in 50 years, and its neighbor across the Delaware River is trying to understand how.Philadelphia Council President Darrell Clarke and Councilmember Curtis Jones asked Camden's mayor what's working in his city."Our leadership has been in every sector of this community," explained Mayor Frank Moran.Philadelphia's City Council says it was hoping to learn more about the relationship between crime and poverty there, which is the city is trying to address with its new poverty action plan."The levels where we have high crime rate like the 22nd district, the income levels are not where we need them to be," said City Council President Darrell Clarke.To better explained how Camden has changed, the mayor took his guests to the waterfront."If you look around you, you're experiencing about $3 billion of investment. That is all due to the incentives that were offered by the state over the last 5, 6, 7 years," said Moran.Councilman Jones says he will take some of what he learned and bring it back to Philadelphia."One thing begot the other in Camden. You reduce crime, you increase investment, you reduce dropout rates and increase graduation rates. And it's not a bad view," said Jones
