Slobodan et al,
"Using numbers from the Centers for Disease Control and Prevention, we found that from 2001 to 2013, 406,496 people died by firearms on U.S. soil. (2013 is the most recent year CDC data for deaths by firearms is available.) This data covered all manners of death, including homicide, accident and suicide.
According to the U.S. State Department, the number of U.S. citizens killed overseas as a result of incidents of terrorism from 2001 to 2013 was 350.
In addition, we compiled all terrorism incidents inside the U.S. and found that between 2001 and 2013, there were 3,030 people killed in domestic acts of terrorism.* This brings the total to 3,380."
2,996 people died in 911, my quote.
I'm not into America bashing, however you seem to have a major problem that is not being addressed. English is the lingua franca of the world and as the largest English speaking country in the world you command attention, good and bad.
Actions speak louder than words, "406,496 people died by firearms on U.S. soil" since 2001 speaks loudly to me (oh! add another 70,000 odd since then). What is scary is the numbers are close to half those in the Iraq, a deadly war zone.
Something to think about…
