All 3 explanations are wrong
How you would handle situations :
RDM : dont give a verbal unless proof or you know he did it, just keep an eye on him
NLR : Ask for proof
Metagaming : Freezing them for 3 minutes making them read the rules is harsh, just explain the rule and give him a verbal to begin with and if he does it again warn him

-Support for now
