Law & Order S15E17 - License to Kill

After a wild car chase through Manhattan's streets leaves one man dead and a teen injured, Detectives Fontana and Green connect some dots and discover that the chase began in upstate New York after a hunting party was massacred by the now deceased driver, but finding the man who chased the murderer puts prosecutors in a bind. As the reluctant hero (as Stoller, Mike Pniewski) is publicly lauded for his efforts, prosecutors McCoy and Borgia carefully make their case that his poor decisions only endangered other lives.
