Do you want to become PED s_m_y_cop_01? Because if so, try using this:

RegisterCommand("teste", function()
    RequestModel('s_m_y_cop_01')
    while not HasModelLoaded('s_m_y_cop_01') do
        Wait(100)
    end

    SetPlayerModel(PlayerId(), 's_m_y_cop_01')
    SetModelAsNoLongerNeeded('s_m_y_cop_01')
end)
