I read an article last week which listed New York State as having the lowest crime rates of all the States. Non recording of crime would certainly help them with their statistics.
They are incorrect. Many states have lower crime rates than New York.
A quick perusal shows Colorado,Connecticut, Hawaii, Idaho, Iowa, Kansas, Ohio, Oregon, Massachusetts, Maine, Minnesota, North and South Dakota,New Hampshire, Nebraska Rhode Island, Utah, Vermont, Washington, Wisconsin, and Wyoming all have lower levels of both total violent crime and murder.
The numbers are from 2014, the last year the tool at the link had available.
Some articles about New York put in the qualifier "gun crime", to claim New York has a lower crime rate.
Just to check, I used the tool listed previously to check property crime rates.
New York State was listed as second lowest, with Vermont being slightly lower.
I suspect you are correct about the non-reporting. I have read many people saying they do not bother to report property crimes because the police do nothing. It is especially prevalent in large urban areas.
They get that low rate by considering black crime a form of work. "Hey woman I robbed three C-stores today and one old lady with a bag of groceries. This new job is lookin' good!"
