Me and my friend were talking outside having a normal conversation. Where we live the homeless population is a huge problem. We see this homeless dude get close to a lady and began touching himself. I get in between of them and the my friend grabs from the neck and moves him away. We both call him out on his BS for being a pervert and his friend hands him a knife. He pulls it out and starts threatening both of us saying he’s going to stab us and wants to spill our blood on our floor. He doesn’t do anything and then leaves while he keeps threatening us as I call 911. I then get notified by police he got arrested. A month later the prosecutor calls saying he ended up in jail for a month and pleaded guilty with a plea deal.
