Milwaukee has seen twice as many murders this year as it did in the first half of 2014, according to USA Today. Baltimore, New Orleans and St. Louis saw spikes of 33% or more, and cities like Chicago, Dallas, Houston, New York, Philadelphia and Washington, D.C. have also seen increases.

It may be too soon to say whether this is a trend or an anomaly —i ndeed, several major cities have seen decreases in homicide rates, including Indianapolis, Los Angeles, Phoenix and San Diego. While some experts say the numbers reflect a struggle on the part of law enforcement to fund the necessary programs to keep decreasing the homicide rate, others say the numbers may even out as the year progresses.
