If social media companies exist to collect massive troves of personal info from users--and they do--then there is a valid national security concern over social media controlled by an adversary. This is distinct from the individual privacy concerns towards domestically-controlled social media.
The same day [April 12, 1945] I saw my first horror camp. It was near the town of Gotha. I have never felt able to describe my emotional reactions when I first came face to face with indisputable evidence of Nazi brutality and ruthless disregard of every shred of decency. Up to that time I had known about it only generally or through secondary sources. I am certain, however that I have never at any other time experienced an equal sense of shock.
I visited every nook and cranny of the camp because I felt it my duty to be in a position from then on to testify at first hand about these things in case there ever grew up at home the belief or assumption that 'the stories of Nazi brutality were just propaganda.'
Some members of the visiting party were unable to through the ordeal. I not only did so but as soon as I returned to Patton’s headquarters that evening I sent communications to both Washington and London, urging the two governments to send instantly to Germany a random group of newspaper editors and representative groups from the national legislatures. I felt that the evidence should be immediately placed before the American and British publics in a fashion that would leave no room for cynical doubt.
Fuck social media, why doesn’t everyone have a geocities page with a webring that links to their angelfire page and guestbooks and ICQ and stumbleupon KIDS NEED TO STOP HAVING A DIFFERENT INTERNET EXPERIENCE THAN I GREW UP WITH!”
The building manager should (and may be legally required to) have a fire department approved emergency plan that specifically addresses this question. Usually, the plan will be for you to await rescue.
A modern, up-to-code high rise building will have designated "places of refuge" that are designed to withstand heat and smoke, such as a pressurized stairwell with fire doors. In older buildings that don't have something like that, the plan might call for disabled people to go to the nearest (unprotected) stairway, or it might call for them to remain in their office/apartment and "defend in place". If possible, call 911 (or equivalent) to notify rescuers of your location.
How many assholes have we got on this planet anyhow?
