Tackling an active shooter? I ain't Hussein Bolt...so there is little chance I am going to have the speed to actually take someone down from anything outside of what would be considered h2h distance anyway.
Funny how many people aren't Hussein Bolt and who stop shooters by tackling them. Funny how so many have no real training in such matters. Funny how many people inside of H2H distance don't do anything to stop the shooter. Funny how sometimes people outside of H2H have to work to get to the shooter to stop him/her.
You don't have to be Hussein Bolt to make a difference, but you need to be smart about your actions.
