I'm hesitant to attempt to correct anyone with a "juniper.net" address, but I'm not sure this is entirely true.  Discarded OSPF packets should show up as layer 3, not layer 2, so I don't believe policed discards counts in this situation.  It is correct that CDP/LLDP/VTP/etc. will show up as policed discards.
