This isn’t as sensational as the headline appears. It’s just an entry. Surveillance could easily be overlooked but it’s why she drove to DC.
In this brief piece under her name, you can see they made her into a complete mental case.
Just a slight mention of her believing Obama had her under electronic surveillance. She worked for the dentist for 8 years! He said she was always happy.
I guess it is likely that she got some kind of mental breakdown (the testimony of the boyfriend). OTOH if what you wrote initially that she met and befriended Obama is true, then she may have ended up in a surveillance net. Bad technique may well have made her listen in on Obama’s conversations IF HE ALSO WAS UNDER SURVEILLANCE.
Just a brief story: After the murder of our PM Olof Palme in 1986 the older brother of a friend of mine was investigated (along with 100s others). He had nothing to do with the case, but had been stupid to say something less than comlpimetary about the PM where he obviously had been overheard by someone who did not like it. My friend and his brother shared a flat, and furing several months their phone (prior to cell phones) started to behave strangely; signals at odd times, strange voices during regualr calls, duoble signals when call were finished etc. Then after more than 6 months the brother was suddenly called to the police. Well, he had a pretty good alibi since he had been on a skiing holiday when the murder took place, so all well and good. But about a week after his vist to the investigators, suddenly the phone was alright again. Obviously they had been under surveillance.
