Chapter 7: Do not harm R&R
Do not mess with R&R unless they are going against your directives to offer services to another player.
Citizens can only order a medic to revive a deceased player that is requesting medical service.
Citizens may only interfere with a medic performing his or her duties by ordering the medic to stop reviving, or not to revive, a player, group, or gang
Doesn't say anything about telling Medics to leave a city. You can tell a medic to perform medical duties or stop performing. Outside of that all you can do is take them hostage.
