You just don´t go over to your neighbor carrying a gun, they had bad intentions.
As for the guy flipping out, imagine being pointed a gun because of some mattress in the trash and you are with your FUCKING KIDS, how surreal this is. Advice in your life, if you are not tough enough to talk/confront people unarmed don´t start shit up.
The old man from the get go said he would kill him if he came closer, the guy said many times for the old guy to put the gun away and leave, he chose to stay and confront an unarmed men who was just pissed that two assholes pointed fucking GUNS at him and his FAMILY because of FUCKING TRASH!
