Over the past year, Street, a Democrat from North Philadelphia, has been telling anyone who will listen that a change is overdue. Pennsylvania's murder rate ranks 25th in the nation. Yet, courts in the state sentence people to life without parole at a rate that's among the highest in the country, and more than double the national average. Street introduced a bill last year that would allow lifers to be considered for parole after 15 years — a move that would make 64 percent of lifers eligible for that consideration.
