While adding more police in a city that struggles with crime might seem like a no-brainer to some, lawmakers familiar with the history of Hopkins’ relationship with Baltimore communities say there’s a long-festering lack of trust.

Residents near the Homewood campus successfully fought a university plan to bring in a new supermarket, which the neighborhood argued would hurt a longtime local grocer.
