There is no question that the shooting at the Trump rally is big news. But it is also a good rule of thumb that in the immediate aftermath of unexpected events like a shooting, the amount of actual factual information available is very small and yet the media feel the need to spend vast amounts of time on it. The inevitable result is that you get huge amounts of mindless blathering as news media try to fill the time without having anything to say.
So you will get reactions from politicians who were nowhere near the scene, from people who were at the scene but did not really see anything, and also the inevitable discussion about what this means for the election, again accompanied by speculations from politicians, political pundits, and ordinary people, none of whom really know anything.
Much of the chatter will be about the possible motives of the shooter, whom the FBI identified as a 20-year old man Thomas Matthew Crooks. They have released his name so people have immediately scoured the internet to find out information using that name, in order to seek a motive that will bolster their preferred narrative. But this is dangerous because few names are unique, though in this case having three names narrows things down, assuming that it is correct. I have often been surprised when searching for someone on the internet to find out how many people have the same name. In addition, inferring motive from biographical data is a practice that has dubious value.
I find it helpful at these times to just tune out the news and occasionally check the headlines to see if anything new has been discovered. It is best to wait until firm information is unearthed before forming any conclusions. In the words of Sherlock Holmes, “It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”
