“SWATTING” – Swatting is the tricking of any emergency service (via such as a 9-1-1 dispatcher) into dispatching an emergency response based on the false report of an on-going critical incident.  (link)

LAKE MARY, Fla – Lake Mary Police are now questioning the validity of several  statements Shellie Zimmerman made when she told 911 dispatchers her estranged  husband, George Zimmerman, threatened her and her father at gunpoint Monday  afternoon.
“We did not find a gun, did not locate a weapon,” said Zach Hudson, public  information officer with the Lake Mary Police Department.  “Nobody ever saw  a gun. A gun is not part of this story.”
Still, a gun was at the crux of the account Shellie Zimmerman provided to 911  dispatchers when calling for help.
“He continually has his hand on his gun and he keeps saying, ‘Step  closer.’  He is just threatening all of us,”  Shellie can be heard  telling dispatchers.
Hudson told ABC Action News Shellie provided a written statement Monday night  saying she never saw a gun and only assumed her estranged husband was carrying a  weapon because he touched his stomach.
[…] “He accosted my father and then took my IPad and then smashed it and cut it  with a pocketknife. I don’t know what he is capable of. I am really really  scared,” Shellie told dispatchers.
According to authorities, Shellie’s father did not have any visible  injuries.   In the 911 call, Shellie asked the dispatcher to send paramedics because her  father’s nose looked like it was broken.
[…] Shellie told dispatchers that officers arrived and had their guns  drawn.  She said George was sitting in his car.  Fearing George would  start shooting, she told the dispatcher her and her father were going  inside.
According to police, George was not in his car when they arrived but was  standing in the yard.  They say he was also very cooperative and allowed  police to search his person.
After being questioned by police, Shellie left the home with her  attorney.  (read full article)
