At a press conference Thursday afternoon, the DA fired back.
Following his announcement of federal charges against a man who took a plea deal with the city in the robbery and shooting of the store owner, McSwain said Krasner was unethical in not telling the victim before the plea.
Krasner pointed to the prosecutor handling the case, and said she never consulted a supervisor nor the victim.
"That was wrong, that should not have happened, that was ultimately my responsibility," Krasner said.
McSwain blasted Krasner for how he has handled victims and their families as the city's top prosecutor.
"There is a state law, the Pennsylvania Crime Victims' act, and he is violating that, and he is violating that routinely," McSwain said.
"He has such disdain for victims, how can you call that justice?" he added.
But Krasner says they have implemented new programs with grant money to help bridge the gap.
"Mr. McSwain is speaking from the bankrupt philosophy that the way that you care for a victim is simply to try to get tons of years, or simply to try to get a death penalty, that is not what victims need. It is not necessarily what they want and it does not make society whole or prevent crimes in the future," Krasner said.
