Propaganda of Gun Laws with Mass Shootings

Have you wondered why there's propaganda so much for shooting? Currently the government is designing a plan to put metal detectors in university's, hospitals, pharmacy, etc... while sounding like a great idea, in the long run it will ultimately lead to invading our privacy and creating crimes amongst citizens. It's a plan to make billions and billions of dollars. Ultimately through constantly making propaganda in news with constant fear, will slowly and gradually increase the popular vote till the government will strike with the idea when it's in their favor and they gain more support. My estimate is by 2020, 2021 this will be more of a reality to fight off "Terrorism"... an excuse they use for every new bs law. Think for yourself and always question mainstream media. Do your research and stop being gulliable right away. Thanks for reading.
