I don't know almost everything about Slovak politics, but I want to think that as a democracy that it is, this man had the support of, at least, a very important part of its population, which is why I consider that any attack against him is an attack on the entire people of Slovakia and its political system. I hope this is the work of a madman and not an organized network of terrorists.
On the other hand and on a human level, I hope that this man recovers completely and can resume the functions that the Slovak people consider for him.
