You are asking questions which will never be answered. Similarly, tear gas canisters are not available to the civilian population. Who then provided him with military/police ordinance????
Fast and Furious comes to mind.
Killing has been a political option employed since the murder of President John Kennedy by the Lyndon Johnson conspiracy. I am not at all surprised at the hellish killing of innocents, be they civilians or military, for the singular purpose of propelling the candidacy or distraction away from scandal by heartless men and women who view our lives as nothing more than tools to expand upon their self aggrandizement.
Similarly, tear gas canisters are not available to the civilian population.
You can buy them online. I’m looking at the site right now. $16.49 each. Not too bad, actually. 6 ounce size. Not huge, but two or three will clear a room, I’ll bet.
I should hasten to add, this is military grade tear gas; OC/CS. One tear gas grenade will affect an 23,000 cubic foot area in 60 seconds.
Fairly decent body armor selection, too.
