According to the article:
Hughes said no crime was committed and no additional information, including the person's name, would be released.
HOWEVER, the person who made the 911 call most likely identified themself, and 911 calls are something we can FOIA, so perhaps someone should release the name of the fool who doesn't know an EVO from a Glock, and plaster this idiot's name and an MP3 of the frantic call of idiocy that created this potentially deadly situation all over the Internet.
Had this been in MD, DC, or NYC, the guy in the car would probably have ended his call when the .308 round from a police sniper penetrated his cranium--THEN they would have "initiated contact"...
Honestly, I DOUBT this was a "mistake". I think that the person who made the 911 call is somehow connected to the person this guy was having his cell-phone argument with, and they called it in to mess with him, which is even worse than a STUPID person calling in a MWAG call. Maliciously filing a false report is a CRIME, and besides it diverts valuable LE resources away from doing their REAL job, which is catching REAL bad guys...
The caller should be publicly outed, because they are either an absolute fool, or they are intentionally filing false reports to mess with people...
