Lawson (ローソン Rōson) is an NYPD officer who was assigned to investigate the American gun runners known as the Fenians.

Lawson is an African-American man with a skinny build, short black hair, and a thin mustache. He wears a flight jacket, dark-colored jeans, and light-colored shoes.

In the early 1990s, Lawson and fellow NYPD officers been investigating Irish nationalist American gun runners known as the Fenians, who were trafficking arms to the Advanced Irish Republican Army. The case was a joint investigation with the FBI and the ATF which occurred over a period of two years. A short period after the destruction of the Advanced IRA in the United Kingdom, the CIA joined the investigation since they and the London police successfully set up a trap for the Fenians in the form of an arms deal when Eda posed as a spokesperson for the Advanced IRA. Accordingly, in New York City the CIA agent met up with Lawson, his fellow police officers and two FBI agents to discuss the details of the operation to take down the arms dealers. During the meeting, the NYPD officer did not speak and listened to Kilner introduce himself and the other men to the CIA agent. In essence, the plan was to pinpoint the license plate of the criminals' cars and have the police carry out surveillance rather than outright ambushing or apprehending the suspects.

After the meeting, Lawson and the other four officers ate together at a restaurant, with an angry Haddock ranting about how the CIA, FBI and ATF only cared about being the lead of the investigation as if it were a turf war while leaving the city police in the line of fire. A day later, they reconvened at the NYPD headquarters to organize their departure. Subsequently, with Eda leading the group of cars, Lawson accompanied Shannon in his car to their destination. On the way to the site where the arms deal was to occur, the Fenians cut off the police from following Eda, who was captured by the arms traffickers. Later regrouping at One Police Plaza, the NYPD officers and FBI agents listened to the ATF agent Dent inform them that one of Eda's transmitters was still active, allowing them to know her real-time location. Once the transmitter indicated a stop of movement, Lawson and the officers headed out to rescue Eda. Lawson was not seen after this and not during the rescue operation either, but in the end the Fenians were taken down, ending the investigation.
