In America, after every crisis, government reacts by stripping freedoms and rights to provide an illusion of security. This methodology is nothing new and, in fact, stems from the work of a 19th Century German philosopher Georg Wilhelm Friedrich Hegel, known as Hegelian dialectic.
Hegelian dialectic usually presents itself in a threefold manner—a thesis, giving rise to its reaction, an antithesis, which contradicts or negates the thesis, and the tension between the two being resolved by means of a synthesis. In more simplistic terms, one can consider it thus; problem → reaction → solution.
If we apply this philosophy to the Las Vegas shooting, the problem is that a crazy person murdered dozens of people allegedly using legally obtained firearms. The reaction is that people are scared and don't want others to have guns and they want to feel safe. The solution, as presented by those exploiting this tragedy for personal and political gain, will be to increase the police state and attempt to disarm Americans.
Like a record spinning on a turntable, this scenario plays out over and over again in America—all while the citizens cheer on the creation of the police state. This cheering is bipartisan as the left cheers for the dismantling of the 2nd Amendment while the right cheers on the expansion of the police state and militarization of police.
Sadly, both sides perpetually forget the very wise warning that those who surrender personal liberty for perceived security—deserve neither freedom nor security.
Indeed this warning is so tried and true that many of those paying attention are able to make predictions based on how the government will react to real or staged events. And, one internet sleuth on 4chan made some incredibly ominous predictions on the Las Vegas shooting and how it will usher in a windfall for the police state.
