Officer Charlie Burnside pulls a prank on Officer Albert Porter, a friend of Reed's, who does not take the joke, and Porter lets Reed know that he feels Burnside is being a little "badge heavy" (rough) on his suspects. After dealing with an inept would-be robber whose car won't start, Malloy and Reed are handling backup on a call when Reed observes Burnside choke a suspect. Reed reports it but nothing is done by the Captain because the victim wouldn't admit Burnside was the aggressor. Burnside turns cocky on Reed saying he has "an ace in the hole" and that Reed was mad about the prank he pulled on Porter. During a foot pursuit of two robbers, Burnside got to one of them and this results in charges brought against the officer, who confronts Reed but this time the other officers back Reed. (thetvdb.com)
