Except that wasn’t the commenters actual argument. It was merely a premise, upon which they argued that LE should be unarmed. I accepted (and clarified) the premise, but pointed out that premise is not actually sufficient.
“It will also be used to subjugate the citizen”
All power can be used for immoral purposes, even citizen militias (like naively extolled by anarkiddies) are perfectly capable of abuse.
The problem therefore is to minimise abuses and the solution is to implement immediate repercussions for immoral actions. Not disarm the police. That does nothing but mean that as long as you have enough bullets, you can run your own unaccountable government.
