Call me cynical. Many of these types of activities are false flags intended as a deception by operatives to stir up the public and create an intended reaction.
Problem one is a controlled media that is in partnership and refrains from investigating, and reporting objectively and honestly.
Many no longer trust even the highest levels of government (ours or others) not to do wrongful and evil things so as to push a political agenda, whether it be gun control, more surveillance, martial law, expansion of the perpetual war on terror, etc.
Corruption and lack of ethics has become the new norm.
