2021 08 26 Biden Post Bombing

Questions:
Who 'instructs' Biden on who to call on? Who are 'they'?
Why did we give a list of civilians to the Taliban? We don't give lists of civilians to our own military in order to grant access to anything...they call in the person's name, the commander of the guard or Force Protection local NCOIC CQ checks the name, calls back & grants/denies entry.
Why did we trust the Taliban to protect the perimeter of the airport if the same Taliban released over 5000 prisoners, many ISIS and ISIS-K, so why?
When the Taliban took possession of the numerous military radios, did those radios have our crypto loaded? If so, did we change our frequency crypto rotas? If not, they could've (& could be) hearing all local US military communications at the airport.
