KANSAS CITY'S WORSENING HOBO CRISIS THREATENED BRITNEY MATTHEWS!!!

Thankfully, she seems fine and she earned a great deal of sympathy and media spotlight for her trouble. 

What might be more important for locals is that this danger confronts EVERYONE who ventures into this formerly posh part of town. 

Deets:

"Ya know, with homeless people around Kansas City, there's quite a few of them and I always try to give them the benefit of the doubt and be nice to them and wave at them and smile and give stuff if I have it -- but like today, this guy really just messed things up."

Matthews -- who's pregnant -- says she was driving through the plaza with her windows open when a man approached her car.

"He kept coming ... and kept coming ... and so finally he was saying something and I was like 'No thank you.' So, I was like rolling all the windows up and right as I rolled 'em all up he starts beating on my car, beating on my windows right at my dogs and the dogs going ballistic."

"So, I just sped off and ran the red light! I didn't even look to see if anyone was coming or anything but you know what, I made it home and that was scary."
