I'm not sure, but if I remember good, you can't use spaces in commands, so you need to do it inside a command:

pawn Code:

if(!strcmp(cmdtext, "/911-police", true, 11)) {
    if(!strcmp(cmdtext[12], "187", true)) {  // If the player typed /911-police 187
        new string[128], pName[MAX_PLAYER_NAME];
        GetPlayerName(playerid,pName,MAX_PLAYER_NAME);
        SendClientMessage(playerid, -1, "Dispatcher: Ok, Please remain calm and stay at your location, assistance will be there shortly.");
        format(string,sizeof string, "Police Dispatcher: All units, we have a Homicide at %s's location, Requesting EMS and Police for assistnace.",pName);
        SendClientMessageToAll(0xFF0000AA,string);
    }
    if(!strcmp(cmdtext[12], "211", true)) {  // If the player typed /911-police 211
        // blabla
    }
    return 1;
}

Been out of scripting for a while, but this code should work I guess.
