First reason:

Код:

SendClientMessage(playerid, COLOR_ERROR, "(TEAM KILLER)");

Shouldn't it be:

Код:

SendClientMessage(killerid, COLOR_ERROR, "(TEAM KILLER)");

Second reason:

Код:

if(IsPlayerCop(killerid) || IsPlayerArmy(killerid) || IsPlayerSwat(killerid) && IsPlayerCop(playerid) || IsPlayerArmy(playerid) || IsPlayerSwat(playerid))

I really doubt that an AND placed in that way would work (It won't work unless playerid is a cop)... try this:

Код:

if((IsPlayerCop(killerid) || IsPlayerArmy(killerid) || IsPlayerSwat(killerid)) && ((IsPlayerCop(playerid) || IsPlayerArmy(playerid) || IsPlayerSwat(playerid)))
