At this point I'm not sure what to believe. There are three outstanding questions that really need to be answered.
1) Do Pelosi's really not have onsite human security when Nancy is not there but Paul is? This seems very odd. They are worth well over $100M.
2) If they don't have human security how did this not trigger an alarm system that would call the police. Any high end home, especially in a high crime city has sensors on all doors and windows and glass break detection. It is impossible the Pelosi's did not have this, especially given we know they have Camera's. The only possible answer I see to this at this point is the system was not armed.
3) Why did the intruder let Pelosi go to the bathroom.
4)Why did he wait to physically attack Pelosi until the police arrived.
5)Who was the "unknown person" who let the police in?
3&4 I by themselves I can explain away given the guy was mentally ill and had erratic behavior. But with the other 3 questions there is just too many open questions here and frankly in San Fran I do not trust the authorities not to lie or change the reported events to protect the Pelosi's.
I think it's very clear what is needed at this point is security footage, and or police body cam footage. If we could at least get security camera footage of the guy breaking into the house I think would pretty much end the speculation on if this is really an intruder and I'd be willing to except the Pelosi's story other than this being caused by far right extremism. Given the suspects past and history of leftism anyone being honest has to admit this is guy is mentally ill and politics in not the driver.
