1. Was there security at the Pelosi home?
Yes, the Capitol Police reported that there were are camera surveilled by the capitol police, but the police is understaffed and underfunded, so the break-in was noticed when 911 was already at the scene.
2. If there was, how did this guy get in?
He crashed through the rear door, just like he confessed to the police.
3. If was none, why wasn't there any?
See answer to point 1. Also, Republicans have resisted attempts to allocate additional funding to the security of Congress members and their families.
4. Who opened the door while Pelosi and his assailant wrestled for the hammer.
Paul Pelosi
5. Why was the glass outside the house if there was a break in?
The nut job said that he had to hammer it several times to get in, so it is very likely that some/most of the glass would be outside.
6. Why are we not being shown the cops bodycam video?
There could be a lot of reasons, maybe because they do not show anything of relevance for the public, maybe because there is an investigation going on? Why would you care in the first place?
7. Why were the cops doing a "wellness check" at the Pelosi house at 2:30 AM.
Because Paul Pelosi called 911.
There are now multiple sources (direct testimony, confession of the perp, cameras, reports from the police etc..) all painting a very coherent story of a M.A.G.A/Q nut job breaking into Pelosi's house to hurt/kill Nancy Pelosi. Now let us know, why are you asking these kind of irrelevant questions? and what do you think are the answers?
