Just for future reference, if you feel like you need to criticize the actions of a staff member or a dev, I'd encourage you to make a ticket and ask for leads / management.
There are ways of elevating an issue that are less cumbersome than creating a fake account and using a VPN and they are there for good reason, because we want you to be able to!
Regarding the claim of metagaming, I think you are a little confused at what actually happened here.
This might in your defence be, because you weren't actually there and are only going off the clip you saw, which is understandable so let me try and clarify a few things and give some context here.
So firstly, I wasn't there in roleplay during the raid, I was in invis mode / in the event menu, coordinating a dev intervention in a situation.
(you can ask the occult member I accidentally flashed my warrant card too whilst standing behind him invis 
)
Secondly, the communications in staff-int were as I said to coordinate the dev intervention, and didn't really have anything to do with the tactics of the police raid.
I was communicating with Jesse (who was one of the police members leading the police's effort) to make it a little bit more realistic in roleplay, so instead of teargas appearing out of nowhere, the police had to get airlifted to the roof and roleplay dropping the teargas cannisters and flashbangs through the ventilation ducts on the rooftops.
Something like this requires a bit of communication and timing to pull off hence we often use staff chat for it. This is not unusual for us to do in situations like this where devs or staff leads either intervene in situations for whatever reasons or are orchestrating them (mini-events like fires, hacks/security breaches, etc). Another example of this would be for example bomb threats where the one who will set off the bomb (dev / staff lead) is communicating through staff chat with the actual EOD member to make certain things, like the timing of the explosion seem more realistic/natural for the rest of those involved.
If the members actually involved in the situation would like to further discuss the nature of me intervening, I'm happy to do so separately but that seems rather out of scope for this report, considering this is a metagaming report which I think was made due to a lack of context of what was actually going on in the situation.
) As you said above in the future i will make a ticket and request staff leads / management
