Ten seconds over six is an indictment of the SS. Do I think they should have saved JFK? No, but there should have been a quicker reaction. Yes, easy for me sitting on my butt to say that.
The training is probably much better today. For example, there probably was little evasive driving training with a limousine in 1963.
As to Biden: I voted for him (Harris is completely unqualified for high office) but for a Republican Senator, i.e., divided government. That looks to be what we got. I didn't expect a Biden blowout but it looks like it's going to be something around 272 or so. He's going to have to moderate his policies if that holds up. The hard left (or hard right) won't like it but too bad.
Well, Biden said he is and will be moderate. The only "radical" thing the Obama Administration did was Affordable Care. Trump sees himself as a moderate, so anything short of racist dog-whistles and not raising taxes on billionaires and large corporations will get Biden labelled a Communist.
As to the electorate: our liberal press and elites simply cannot think beyond race. They think black and Hispanics are over there; and whites over here. There's much more diversity within those groups than the liberal/left realizes or wants. That's a great sign for the country. A white party and a non-white party is not good for the country.
Trump took most of the Confederacy, the Civil War border states and upper North-Midwest. In other words, those areas that spawn White Power groups and have a nasty history of treatment towards minorities. His strength in other areas of the country was in the rural areas, not metropolitan, and he slipped among suburban women.
