I believe the assassination attempts are not random occurrences, but rather are aimed at people who threaten the establishments power.
Found this on at Wikipedia. I usually don’t quote them, but this list seems partially pertinent to the point.
Four sitting presidents have been killed: Abraham Lincoln (1865, by John Wilkes Booth), James A. Garfield (1881, by Charles J. Guiteau), William McKinley (1901, by Leon Czolgosz), and John F. Kennedy (1963, by Lee Harvey Oswald). Ronald Reagan (1981, by John Hinckley Jr.) is the only U.S. president to have been injured in an assassination attempt while in office and survive. Two former presidents, Theodore Roosevelt (1912, by John Schrank) and Donald Trump (2024, by Thomas Matthew Crooks) have also been injured in attacks.[2]
There’s more of course. Martin Luther King, RFK. Charles Caldwell. Jose Francisco Chavez. John clayton. Linda Collins. James Garfield.
This is hardly a complete list but do you know what all these individuals have in common?
The answer is that they each were a serious threat to the political establishment.
