Seriously though, I've never heard of them just busting in. If it was a hang up call then they would just knock and say "We got a 911 call that was traced here, we're just making sure everything is ok." That's what they do on Cops. I've never heard of a fucking squad like busting in like "Go, Go, Go!" "Let's move out!" unless someone called and said like you're harboring terrorists in your home and have a meth lab in the back, but what are the chances of someone calling that in. If it was really a mistake hopefully the person that really called wasn't dying at their house, cause they'd be dead now. Those dumb asses didn't even go to the right place. Seriously that's some bullshit. I think you should have a talk with someone.

P.S. I called 911 when I was little and hung up...I was really young and at my grandparents house. When they came they just knocked on their door and said is everything ok and my grandma said yes and they just left.
