Lingle was murdered with a .38 and not a .22 with a silencer as shown in the episode & mentioned by Ness.
Jake Lingle was murdered on June 9th yet when Ness and Malone take him on a ride along to a fake raid , their breath is still visible , the trees are bare and it's snowing , not something you would normally see in June .
When Jake Lingle is walking down the street , he passes by the same window display 3 times .
