In page David I. Shapiro:

"

Throughout the late '80s and '90s, Shapiro began to focus more on mediation. In 1989, he was appointed by courts overseeing the bankruptcy of Eastern Airlines to mediate negotiations between the airline and its unions.[1] In 1996, Shapiro emigrated to London. He is credited in England as a leading mediator, and was said to have encouraged young lawyers to "press the Outrage Button." When asked why he continued to practice law into his 80s, he would reportedly say: "Because I give a damn."[2] On October 1, 2009, Shapiro died of cardiac arrest in London.[3] He had been making plans to return to his law firm in the US, Dickstein Shapiro.[4]
