The truth does indeed matter in a time of universal deceit. When events as tragic and momentous as public massacre and terrorism occur in our open societies, we are immediately expected to acquiesce to public policy changes and new laws. To base such important decisions on phony, incomplete or biased interpretations of events is dangerous.
In order to properly honor victims and those most affected by tragedies as these, true justice and culpability should be the objective, not the advancement of pre-set political agendas such as the expansion of war, increased domestic surveillance, expansion of the police state, government watch-lists, and gun control.
In cases of mass shootings, once an acceptable enough story of events is established, the conversation is hastily directed onto gun control, and any subsequent investigation and forthcoming evidence becomes irrelevant to the advancement of this agenda. The whole truth is never really known or completely understood, thus no meaningful solution can be duly vetted, which is why so many people are questioning official stories about events like these.
