During the encounter you acted without consequence for your characters life, clearly answering the two gentlemen that 'no' you would not stop moving even though you were outnumbered. Though you are claiming to be PK'd because of jaywalking, you weren't, you were PK'd for failing to adhere to FearRP as stated in General Rule 7. "You must always value your own life through FearRP. Failure to abide by FearRP can result in your character being permanently killed".
You made the situation not in your favour when you pulled out your MP40 and decided to not follow orders. Even in the situation if you were being surrounded by 2 members of a criminal organization that decided to just take you hostage and you failed to adhere to fearRP it would have resulted the same.
Personally, I find it hard to believe you did not intend to attempt to hit the two officers as nothing in your voice, nor your demeanour leads for it to be a accident, nor was there a quick apology of "Sorry! I didn't mean to do that". Furthermore, if you spilled water on a mouse that would most likely not how it would it break, they use physical switches where the electrical state is on and off, if you had such a issue it wouldn't be just once it'd click, it would either stop working, or would be consistently clicking, or chattering, not just "owooooo randomly click when I'm in combat".
I summary I believe R4GED alongside Tomahawk made the correct decision in the PK, regardless if you think it wasn't valid for them to ask you to stop, you must act in a way to value your life especially if you outnumbered otherwise you can expect to be PK'd.
I'd recommend reading the rules as well as the PK guidelines to ensure you are aware of what actions result in character death, I believe a permanent PK was fair enough and a temporary is not needed as the situation is extremely clear cut. You did something without expecting the consequences and failed to take it seriously as such you dealt with the consequences.
Just to add for information, temp PKs are reserved for COs, not a feldwebel.
