This site is worthless..... They are including cases that are PENDING or CHARGES DISMISSED . Which means either they have not been found guilty or had been found innocent/good shoot. There were 21 cases in the Private Citizens Killed that were either Pending or Dismissed, some of which included more then one killed.
Also this site list the same people under multiple categories such as Private Citizens Killed, Mass shootings, Murder Suicides. Michael McLendon is listed under all three.
Lastly, it also counts the suicides into the numbers.
Even still let’s look at percentages..... In Florida we have around 800,000 active permits, res and non-res. So 77 out of 800,000 permits is 0.000096% and that just counting Florida's permits.
