The Orlando massacre, while tragic, would have to occur daily to crack the top 5 causes of death. Even then, I'm not sure it would. If you took the combined global death tolls of every terrorist act in the last two decades and condensed them into a single quarter, then put it on repeat, it still wouldn't make the top 5 annual US deaths. Terrorism is vastly overblown as a threat to any of us.
If it's not among top 5 causes of death, then it's not important enough issue to do anything about. NSA spying, patriot act, TSA, etc. meh, unimportant stuff that we should just ignore.
Far more damage is done to our daily lives in the name of stopping terrorism than has ever been done in the name of it. So, I agree the best solution is not to do nothing - the best solution is to dismantle all the somethings people have done in the last two decades under the guise of protecting us from terrorism.
Oh, government overreach has entered top 5 causes of death list? Or could it be that issues that YOU don't care about can be dismissed by "doesn't crack the top 5 causes of death" test but issues YOU care about is huge threat to all of us even if death caused by it are basically zero? Well, that's convenient.
