Rule #5 refers to verbal abuse, not abuse of in-game mechanics, this is covered by rule #3, rule #9 etc.
Therefore your breakdown on why you didn't break the rule around abuse would be somewhat void - as that's not the reason you seem to have been jailed.
In your report you admit to hitting players with your nightstick and 'trolling' them as you put it.
You have also said you threw a flashbang in a bank full of players who you knew were not wanted, and you did so twice - with the second being a misclick.
This would fall under the following rule/guideline;
With this in mind, would you argue that your actions of hitting unwanted players with your nightstick and throwing a flashbang into a group of players you know not to be wanted is not "interfering with other users gameplay in a negative way, which is not an intended part of the game"
From our perspective, flashbangs were not added with the intention to use or harass unwanted criminals with them.
The nightstick was also not added to be used to beat unwanted criminals.
Before going forward I'd like to hear your defense for the rule/guideline you actually were found in breach of.
