Because time travel is a passport to all kinds of excitement and adventure and God-knows-what-else, not to mention opportunity and great wealth.
Would I visit Dealey Plaza on the morning of 11.22.63? Yes, but not to alter history. In his novel and miniseries “11/22/63”, King has suggested what a screwed-up, tangled-up cosmic malfunction would result if anyone tried, so let’s leave it there.
Instead I would become the photographer and documentarian who removes all ambiguity.
I would get hold of three 16mm color cameras with long-lasting magazines and professional-class zoom lenses along with some first-rate Hasselblad still cameras, and hire a couple of assistants.
I would then (a) find a good vantage point and film Oswald (or whomever) shooting from the sixth-floor window. I’d also (b) film whatever actually happened (or not) behind the wooden grassy knoll fence. And most importantly I’d (c) capture some first-rate MCU color footage of JFK and John Connolly as the shots ring out.
