I do see where you are coming from on this issue, however escalation wouldn't necessarily be the proper term for this, I would say this is mainly related to rp standards. That being said there is a pretty large disconnect from the combat systems in game and attempts to rp. Most of the time in sec vs antag, there is a feed back loop that just leads to both sides not wanting to be cheated out of their round, so they move to handle things quickly/not rp situations out.
A good example of this was just the other day for me, where I had an office come up to me asking for a search after I had just grabbed one of my objectives. Given I had tools from a surplus crate include a dsword, rather than murder the officer I had chose to try and rp the situation out, trying to talk and holding a grenade with the intentions of rping out a one time walk away bomb threat. Needless to say my talking was interrupted by two silent baton hits and a wordless walk to the brig. When questioned about why a solo officer would charge a bomb threat, the responses were in line with "I'm not afraid of death", and "I've been hit with worse", which truly is peak rp.
Case in point, the current system is in a feed back loop of sec wanting to red text at all costs with no sense of self preservation, and antags going hard and often cutting down sec when possible. I do think that there should be something set in place to fix this system, which I am curious to hear ideas for.
