Pretty frightening stuff, Barbara.  Glad your family wasn't hurt.  Now let's look at the numbers.

 - In 2015 19 Americans were killed in the US by known or suspected terrorists (Chattanooga and San Bernadino mainly).  The average for the previous 10 years was under 6.
 - In 2015 21 people were killed when toddlers got access to a handgun.  19 were the toddlers themselves.
 - The annual average number of Americans killed by lightening is 33.

So let's back off on the hysteria, OK?
