Dozens of widows of NYPD officers slain in the line of duty joined the Patrolmen's Benevolent Association in demanding that a loophole that lets cop killers back on the streets be fixed, according to the New York Post .
The longest sentence for criminals who killed cops before 2005 was 25 years to life. Those killers — who are eligible for parole after serving 25 years — are now benefiting from 2011 guidelines that look at what criminals have been doing since their incarceration, rather than just the original crime.
