Sort:  

crowds are target rich environments for mass shooters
or terrorists.
don't be a target.

They have to have their sights set really low... The only places I go are the donut shop and Wally World!

they're not looking for quality.
they're just looking for people who can't shoot back.
frankly I'm surprised that WallyWorld hasn't been hit...yet.
a terrorist would blend right in...no one would know until it was too late.
