It’s not at all intuitive for members of the same fleet whose wrecks are NOT flagged as someone else’s, and we loot them freely, to then ban us from destroying the fleets’ wrecks and get CONCORD’d as a result.
Often when waiting on an MTU you don’t need certain wrecks to be dragged in or you may simply want to destroy the wrecks - disabling safety to do so inappropriately causes CONCORD to engage. The warning from Safety is unfortunately an ‘alert fatigue’ item whereby it’s easily ignored as 'that makes no sense, it’s “our” wreck so that must mean something diffrent to me".
I do hope that the fleet container matter can be addressed for the general community. It’s confusing to players who may loot their fleets destroyed ships but couldn’t destroy them. I concur that the safety measures provide a general warning but it’s much too categorical to drive home the consequences of one of these actions in this particular example. This in turn leads to getting criminal flags easily in high-security space, for example, by accidentally engaging friendly targets (especially when using multi-target weapons) or providing remote assistance to friendlies with active Limited Engagement.
