Matthew Belinkie graphed how all 456 episodes of "Law & Order" ended and compared the results to real life:
Over the entire run of the show, more than a third of all the episodes ended in Guilty verdicts, while another third ended in plea bargains. 80% of episodes ended in solid wins: either Guilty verdicts, plea bargains, or implied victories. That’s not too shabby, considering that the actual NYPD has a homicide clearance rate of about 50%. … Another thing that’s not realistic is that there are more Guilty verdicts than plea bargains. In real life, about 95% of all felony convictions are pleas.
