1. Not sure

If you meant that none of the thousands of people who died of gun deaths caused flags to be flown at half staff was inclusive of the mass shootings you mentioned, but Sandy Hook, Pulse Night Club, and the Las Vegas shootings were marked by flags being flown at half staff.

I agree with you that Kirk's shooting doesn't warrant the honor, but I wasn't sure if you were saying that none of those other incidents got that mark of respect...but they all did.
