Time published a chart of the history of mass killings in the United States the past 37 years. Notably, Democrat President Clinton and Obama were drivers for increasing mass shootings in the U.S.A.
Before President Clinton mass shooting numbers were small- usually in the single digits. During the last year of the Clinton administration that number jumped an order of magnitude to 57. President G,W. Bush saw a rapid decrease in mass shootings back to the traditional single digits- and then President Obama took office.
President Obama had several years with large numbers of mass killings; more than 50. His final year in office had 71 fatalities from mass shootings. President Trump has had to grapple with that number himself. That number is about the new normal, except for the year of the Las Vegas shooting when 117 people died under the gun.
Plainly the Congress needs to take action to stop the mass shootings. More people die in one day from automobile accidents that a few years of mass shootings, and something should be done about that too. Congress should build the wall, keep new illegal migrants out and compel law abiding migrants only to be the rule. Society need have a chance to stabilize, eliminate poverty and increase education and ecospheric health.
What can be done is to stop electing Democrat Presidents, for they are catalysts of hate and violence.
With fewer than 100 people killed from mass shootings annually as the new normal for the U.S.A., the risk of disarming citizens taking that path that leads to the vulnerability of 320 million people instead of 100 is a greater danger. Complete arms control has been the normal state of affairs for dictatorships such as exists in communist countries and socialist dictatorships such as that of NAZI Germany.
Without guns citizens cannot defend against jackbooted thugs that pound on the door in the dark of night. People shuffle off meekly to extermination camps. Jews later burn eternal flames at memorials. Contented socialist elites examine statistics for whom else may require liquidation.
