Who exactly are you trying to defend with this utterly absurd line of thinking. Not a single thing the 911 caller said was a verified fact. The caller said there was "a male black sitting on a swing and pointing a gun at people." How does he know it was a male? Unless he can give specific details on why he thinks it is a male, it is just an opinion. Did he even see the "male's" genitalia? The the "male" could self-identify as transgender or female or genderqueer or gender fluid or even genderless. The caller doesn't know. He's just guessing. How does he know the gun was being pointed
at people, and not just in the general direction of where people just so happened to be located? The gun could have been pointed just a few inches away and not directly at someone.
This is the kind of crap speculation that comes from questions that demand speculation to be answered, all in an attempt to absolve someone of responsibility. The 911 call taker, Constance Hollinger, did not relay all of the pertinent information to Mandl, according to the Sheriff's investigation report. In her interview with investigators, she was forthcoming about everything except on the question of why she did not accurately relay a witness' statement to dispatch. On that question, on the advice of her union-provided attorney, she invoked the Fifth Amendment (which, legally, she can't even do one she's started answering question about the incident).
According to a personnel file
released by the city of Cleveland, a supervisor gave Hollinger a "satisfactory" performance rating in 2013, noting that Hollinger "tends to be abrupt, and disconnect the caller when they are attempting to provide additional info."
There is always the chance the witness is wrong, that the suspect has a real gun, but a witness's description of a weapon as 'probably fake,' combined with a description of the suspect as a juvenile, is very different than a description of an adult holding a firearm that the witness is sure is real. But according to the Cleveland Police's own policy for answering 911 calls, they are to "relay all information included in an incident" to officers responding to a call, including a suspect's "physical characteristics" (the description of "he is probably a juvenile" falls into that classification) and a weapon type and description ("it's probably fake" falls into that classification).
911 call takers and dispatchers do not have the time, the luxury or the resources to determine whether or not a witness' statement is fact or opinion, and to imply that witness statements that might be opinion and/or is not pertinent information and therefor is optional unnecessary to relay to officers is just butt-stoopid.
All of that aside, anyone who has seen the video can determine for themselves that an unjustifiable killing took place. If the police had been given "shot fired, people down" information from dispatch, then a 1.7 second decision to fire could be easily justified. But that didn't happen.
