Nassau County Republicans announced Tuesday their decision to repeal school speed zone cameras.

The decision comes a week after Democrats introduced the repeal bill.

Nassau County Executive Ed Mangano has repeatedly said the speed zone cameras were all about safety. However, some residents call the cameras "scam cams," and say they were about money, not kids' safety.

Meanwhile, a Newsday investigation shows many of the school zone areas were accident-free, long before the cameras were turned on.

Newsday analyzed traffic data between 2009 and 2013 during the hours when school was likely in session and found no accidents in 57 of the 76 school zones.

According to county records, the speed zone cameras have raised more than $16.5 million for the cash-strapped county.

The money is equivalent to over 200,000 tickets.

Mangano issued a statement saying the school zone speed cameras protect children and have cut speeding by 70 percent. Through a spokesman, he said, "The administration will monitor the Legislature's debate, vote and budget amendments." In the meantime, lawmakers will need to find $30 million to replace the revenue the cameras were supposed to bring in.

The repeal measure will be discussed at the next legislature meeting on Monday. As of now, the cameras are still operational.
