How would you have handled this situation?

As soon as he came walking towards my car, gun at the ready. As soon as he threatened me, gun drawn and safety off. After that it's up to him how this turns out.

Someone is waking up with no grampa

how i would’ve handled that situation

He didn't knock windows out for nothing. Dude in the car could of been a stalker/pedo.

What made him so angry? Didn’t catch that part

I carry a .45 he would be on the ground in a bad way

Right to shoot when someone breaks into your vehicle by breaking a window. This is why I carry

With some hollow tips.
