A good electric fence is usually plenty for the 'coons, 'yotes etc. etc. etc. , even a covered run is not always enough for hawks........ the point IS you do all you can do and they still persist (against their nature) to target folk's backyard (often quite small flocks) . NO it's not "their fault" this happens, the protecting of certain BOP despite them being overly aggressive and doing tens of thousands in damage to livestock IS the real problem. The time for "unlimited protection" (which is really not accurate as it IS possible to get kill permits in very limited circumstances) is over (or should be) .
BTW please show where I even "hinted" to "SSS" , I did the opposite in fact and clearly stated I'm not advocating any illegal activity or tactics, then posted some legal alternatives that actually work in placing the natural fear of man back into wild BOP. This is nothing new to me, we have raised large flocks for well over 3-4 decades and now have > 60 chickens currently.
ETA:
Also (as you pointed out) the BOP - Are protected; ironically the other predators we deal with are NOT protected, we can shoot them, trap them - dispose of the problem critters-- unlike the BOP issue . You can "secure them" very well and still persistent BOP will upset them try to kill & eat them. Unlike some (including you it seems) I feel bad for those losing most or all their small flocks to these hawks, thus I pointed out it doesn't have to be that way there are legal methods to educate them we are not running an all you can eat free chicken buffet .
