Something else just occurred to me. Another infamous shooting in that region was the assassination of Archduke Franz Ferdinand in 1914. That set off WW1, as many people know.
Was is less well known is that the Archduke’s assassin was not a troubled lone wolf. He was part of a conspiracy, the Serbian Black Hand.
Time will tell. Perhaps Fico‘s shooter really is a loner. But this is the age of the Deep State. So my default position is to consider a conspiracy.
Then you are what the CIA calls a "conspiracy theorist."
