A large fire destroyed a housing project in West Baltimore. One week after this devastating fire several lawyers from a Greenbelt law firm distributed flyers to the former residents of the project to invite them to a meeting if they were interested to discuss their losses. At the meeting one of the lawyers addressing the gathering offered free legal services of the law firm as a pro bono service to anyone seeking to make a claim against the insurance company which insured the building.

a) Does this action by the lawyers of the Greenbelt law firm violate any ethics rules? If so, which rules are being violated?
