Kevlar isn’t magic. For a pistol round, it might absorb a bunch of the energy, but it’s still like getting kicked in the chest by a horse. And that’s only for one. Or, if they’re ceramic plates, they become much less effective after the first impact.
And that’s for a pistol. Consider if they come to the wrong house and the person at the door has a shotgun.
The problem is that you’re probably not lying in wait with a mythical concealed-carry shotgun. Realistic sequences that have happened in the recent past:
A couple guys wearing utility company uniforms ask to step inside to diagnose a problem. They then jump you and arrest you.
Your camera system stops working due to jamming. Then 15 armed men break through your door and surprise you while you’re asleep in bed.
Several people in the crowd at your kid’s graduation ceremony suddenly surround you and zip-tie your wrists before you realize what’s going on.
You’re going to be dealing with a situation where you don’t see in advance what’s happening, and where you’re confronted with a whole batch of people who are heavily armed and wearing body armor. That’s a situation where one individual acting alone is very unlikely to succeed in killing an assailant with a gun.
