They would rather defend selling armored backpacks for kids, armored classroom doors, doorstops like these, armed guards and hundreds of dead children every year. Than to admit most of their mass shootings could be avoided if they implemented some better background checks.

The average american is so indoctrinated with "best country in the world", they will do insane mental gymnastics to defend their outdated ways. For example: They still regularly use cheques, some hospitals still use pagers, you have to wait 2-3 working days for bank transfers, their citizen registrations is so ripe for exploit they have their numbers printed on paper cards(so they dissolve quickly if lost), fraudlent activity is rampant because of how outdated their identification systems are.

Basic solution: Spend a lot more money on education.
