An advocacy group for victims and families of victims of reckless driving is calling out the city's district attorneys for their repeated failure to file criminal charges against drivers who seriously injure and kill cyclists and pedestrians.

On Sunday, the group Families For Safe Streets will gather on the steps of City Hall to urge the district attorneys for all five boroughs to prosecute drivers that have hurt then or killed their loved ones. The group is lead by two others whose young sons were fatally struck by drivers—Dana Lerner, whose 9-year-old son Cooper Stock was struck by a cabbie last year, and Amy Cohen, whose 12-year-old son Sammy Cohen-Eckstein was killed by a driver in 2013. As with so many other cases, neither driver was criminally charged.

It is exceedingly rare for a driver to be criminally charged if he or she fatally strikes or injures a pedestrian or cyclist, provided the collision was not the result of a hit-and-run, intoxicated driving or an intentional strike. According to data compiled by Streetsblog, only two such fatalities out of over 400 have resulted in a homicide charge being filed against a driver.

"Why is it that if you kill someone while driving drunk, the district attorney will press charges, but not if you kill or maim someone through reckless behavior on the road?" Cohen asked in a statement yesterday. "Crashes caused by aggressive driving are not accidents. When drivers make turns at full speed without even looking, or speed through intersections and kill people, D.A.s never press charges. We need to change the culture on our streets and make it unacceptable to drive recklessly."

Pedestrian deaths did decline in 2014, but there were still 132 pedestrian fatalities as of the end of last year, a far cry from Mayor de Blasio's intended "0" fatalities as part of his Vision Zero initiative. Cyclist deaths ticked up last year. The mayor's plan hopes to eradicate cyclist and pedestrian fatalities by the year 2024, but street safety advocates say that can't happen until drivers face stricter consequences. As Lerner noted yesterday, "D.A.s need to change the attitude that 'accidents happen' and start bringing charges in connection with these crashes, to keep dangerous drivers from destroying more lives."

The rally will take place at 2 p.m. on Sunday at City Hall.
