Here they are again: The Good, The Bad, and The Ugly
According to George Trainor, George was The Good, John was The Bad, and Kenny Driscoll was The Ugly
All three were fine with their titles, as they made a great team of police that did the job and did the job well.

This is Kenny looking under the car to make sure no-one or nothing is under the car before it is towed.
Ken was told it looked like he was falling out of the car, So they took the picture for the joke. BTW It is
John Calpin is toward the front of the car; he is acting as if he is directing Ken into the parking place.

This picture was taken the day Ken and John seized a safe containing 2 keys of cocaine. They tripped over it while chasing a suspect who bailed out of a stolen car and ran into an apartment. Since he was running from the police, when they knocked on the door, a lady answered, telling the officers she was alone and no one should be in the apartment with her. They went in and found him hiding in a closet in a near-empty room. The lady obviously living there said she wanted the suspect removed, and she told them to take the safe out too. Long story short, her boyfriend rented the apartment but only furnished one room for her. The other rooms were for his stash house. So, the suspect that was running in and out ended up getting a ten-year sentence for the drugs.

Ken Driscoll is in the wheelchair, with John kneeling beside him.
These two were partners on a midnight shift for four or five years
back in the early 1990s and made some great cases. They took a
lot of guns and drugs off the street, and made a lot of arrests doing it.
Ken misremembered a line from an old movie, Next of Kin. The
line was, "Yeah, we made a mean pair too." The brothers were
talking about the fights they had been in, and one said, "We had
some doozies," to which the other brother replied, "Yeah, we
made a mean pair too." However, Ken always thought he said, 
"Together, we made a mean pair of two," and Calpin and Ken did.
The names Calpin and Driscoll were legendary from those days.
