j.r. pleads guilty to grand larceny. habitual criminal and given ten years to life behind bars. in watching the raw video of our investigations following the las vegas police department, two things struck me. one, it really gives the sense that the police are out there doing more than just reacting to criminal activity, that they're being proactive, even creative in their attempts to protect their citizens. and two, that there are criminals out there, guys like todd and rusty and j.r. who consider their job to commit crimes, looking for opportunities every day. it's truly the age-old tale of cat and mouse, cops and robbers. and the cops are clearly doing their part to stay one step ahead of the robbers. that's all for this edition of "vegas undercover raw." i'm chris hansen. thanks for watching.
