The hypothesis about the crime rate rises with hurricanes and bad weather.

Crime has a correlation to weather.

Hypothesis: Nitrogen + virus + depression schizophrenia etc a sum leads to murder and mass murder.

Could be simply nitrogen causes higher murder rate, thus in hurricane season, as that brings nitrogen, especially when taking nitrogen out of the ground when the hurricane fills up with elements and, later on, let lots of it out during the storms, so people than have suddenly a lot of these elements in the environment.
