To start of I don't know this cop and I have never watched his stream.

I watched the whole situation from several perspectives .Before I start I just want to clarify what meta gaming means in simple words : When your character knows something he can't know .

1. The clip is out of context . Mexi's character already knows the guy he asked chat about .He talked with him in the bank robbery 1~ hour before this happened . Is it meta? No, because he knows him .Is it wrong ? I don't think so either, if you watch any other streamer you will see chat helps them too and sometimes they ask chat directly about things . There is no difference
2. I love how everyone goes "Meta" when the cop calls for backup in the hospital. The cop chased the SAME white car in grandma's house few minutes earlier and the robber fell from the car when he went for a pit . So calling backup was the right choice and not meta whatsoever.
3. About him camping grandma's house, is it meta? Again no because 2 criminals were injured from the bank robbery. You could say he "watched Buddha's stream" or such but it can't be proven because what he did makes sense. Is camping an asshole move? Maybe..
4. The only rule that he broken is fail RP when he was dead on the ground after the shootout and told the cops where to go and such . Does he deserve a punishment for this ?Maybe, that's for the server owner to decide

You guys forget this is RP and everyone trying to have fun . You guys taking this shit way more seriously than it should be and it ruins it for everyone .Most of the streamers don't give a shit about meta and just want to have fun.
