Dying in the line of duty seems like it's more than fair to me. To remedy the risk, a greater reward should be given out to units that participate in sweeps. Based on their performance, this can range from an outright promotion to a hefty SC reward. You can argue that rebels have more agency when it comes to their actions - and they do - but they are just as critical to the server as Civil Protection is.
As things stand, the squad system already had the major drawback that it's completely static. At some point, the i2/i1 cap is going to be reached, and any and all ranks below that are essentially stuck in limbo. I recall a rank leader that already died 3 times, and they still manage to hold onto their position. This, I think, is a deeper problem that has to do with the distrust of the current faction leads for units that are not in their direct circle. I don't think being a rank leader is necessarily so challenging as some make it out to be, and I welcome the idea of a more fluent system that will allow people of different styles to breathe fresh air into the faction.
The current situation is that, until perpetuity, the same people will always be in charge. You will forever have the same NCO's, with the exemption if they get booted from the position due to some OOC fault (which, in my opinion, is already extremely lax. If multiple counts of power gaming and a count of RDM isn't reason enough to reduce a rank, then I don't know what is). The sense of progression will inevitably stagnate until mid-and low-tier cops get bored and stop playing.
A dewhitelist is extreme. An outright reset to i5, I feel, is as well. I propose a middle ground where all units - excluding rank leaders - get lowered by one rank. Rank leaders themselves should also not be exempt from this, but I recognize that their role is of somewhat significance. I have thought of two situations for that:
A) Either rank leaders are put on a life system. If they somehow die more than 3 times, they are PK'd and removed from their position.
B) Rank leaders fall under the blanket rule of derank upon death. To not entirely destabilize the faction, it should be enforced that they *always* have a second in command that can take over in case of death.
Frankly, the entire system is super stagnant right now. There is no challenge as a CP. No sense of urgency or danger. Losing a rank is shit, but so is getting PK'd, and every other faction has to deal with that every day to uphold their role in the server that already shafts them on nearly every other front. I'm a cop main, and I think harsher PK rules will bring about a positive change that will see competent cops rewarded.
