3. BACKGROUND FACTS
9
Dr. Clifford Stott, PhD, is considered to be the world’s premier expert in the field of crowd
10
policing. 2
11
He is a professor of social psychology at Keele University in England and the director of
12
the Keele Policing Academy Corporation – a strategic research center that specializes in police
13
related research for the University. 3 He is current the visiting fellow in the Department of Crime
14
Science at the University College London and visiting professor in the John Glenn College of
15
Public Affairs at Ohio State University. Previously holding similar positions in Denmark,
16
Australia, and the UK. 4 He has been associate editor for the British Journal of Social Psychology,

the European Journal of Social Psychology, and Policing and Society. 5 His trove of scholarly
2
articles are set forth in his CV.
3
Professor Stott has managed millions worth of research grants and income from research
4
counsels, governments, police forces. 6 Although he is currently research focused, he has taught
5
throughout his career including social cognition, group crises, and crowd psychology. 7
6
In December 2020, Professor Stott, through his consultancy company, was hired by the
7
Defendant’s Office of Inspector General (OIG), in relation to the City of Seattle’s Sentinel Event
8
Review. 8 According to SPD Chief Diaz, the Sentinel Event Review replaced the After Incident
9
Report which would generally follow a significant use of force event. 9
10
As the process developed, Professor Stott became more involved in helping the OIG to
11
make decisions about how it was managing the Sentinel Event process, particularly, the extent to
12
which the empirical analysis was underpinning and informing it. 10 Ultimately he published a 60
13
page report with the involvement of the OIG regarding wave one – the first four or five days of
14
protests. 11 The team of analysists from OIG were assigned to the sentinel event review and were
15
involved in the day to day organizing, gathering, and analyzing of data for that process. 12 The
16
Professor helped to correct the OIG’s work and built a more accurate interpretation of data and
17
chronology. 13
18
For example, when viewing body worn video (BWV) provided by the OIG and SPD, he
19
noted a rapid deployment of a blast munition by the police where people were “clearly very, very
20
frightened and fleeing in fright.”

Professor Stott formed forensic opinions which he set forth in an audio PowerPoint
2
presentation and his report. The audio version of the PowerPoint was not provided in discovery,
3
but the PowerPoint and the written transcript were. 14 From the Professor’s perspective:
4
[W]hat is important to me analytically and empirically is that the police don’t say anything. The police officers just are not saying anything at all. They’re just standing there. They’re not trying to de-escalate the situation. They’re not trying to communicate with people. There’s simply just standing there in a corner in a cordon with these people trying to get some sort of explanation out, which is an incredibly important point in terms of the nature of crowd psychology and what we know about effective crowd policing which is characterized by good dialogue. 15
5 6 7 8
“[I]n my opinion, the Seattle Police Department did not utilize dialogue as a de-escalation tool at critical junctures. And had they had the capacity to exercise dialogue, then it’s very likely that the pattern of events would’ve evolved in a fundamentally different way and that they would not have experienced the rioting that took place that day.”16
9 10 11 12
At another point he addressed a SPD leader’s characterization of the gathering as being a “riot.” “And the extent to which you can define a crowd of probably in excess of 3,000 people at a minimum as a riot where two incidents of confrontation involving essentially two individuals is a riot is I think a very, very questionable decision.” 17
13 14 15 16
Regarding the pushing of protesters who said, “don’t touch me,” leading to the deployment of chemical sprays, baton, and bikes, the Professor stated:

“[I]n my opinion, the move to the use of chemical weapons, chemical spray, was very quick…tactical communicated verbal interaction to relatively high-level use of force occurs in a few seconds, and that is also in a densely crowded situation where other people are directly affected by these munitions who are merely peacefully protesting. I think that raises all sorts of issues that are problematic for various reasons.” 18
4
He explained the importance of chronology and understanding it in the context of crowd
2
5
science:
7
“I’ve seen multiple—multiple studies we’ve done – we’ve done on riots. You get that sequence of interaction that the collective conflict flows after indiscriminate police use of force.” 19
8
Q.
And that is what happened here in your opinion?
9
A.
It is. 20
10
Professor Stott also noted that during the first wave, when police made announcements
11
such as to disperse, “it would’ve been very, very difficult for the people in the crowd at the
12
point…to have heard that announcement.” 21
6
13
That Monday outside the precinct, Professor Stott found no evidence of direct physical
14
conflict or sustained missile throwing at the police, before the police deployed use of force against
15
the protesters. 22
16
He opined that the police “incorrectly assumed that once a crowd begins to exhibit even
17
small amounts of violence, that they would then interpret that as a shift to the classical crowd
18
psychology. And it was that that then leads them to apply this escalatory form of policing.” 23

6 7 8 9 10
•
$74-77,000 for two-day training packages for the entire command team; and
•
$60,000 for the work on the Sentinel Review Process. 25
Defendant did not retain Professor Stott as an expert witness in this case. After receiving his (at times blistering) critique on Wave One, the City did not request that he continue to assist Waves two, three or four of the Sentinel Review Process.
11
4. AUTHORITY
12 13
During the deposition, defense counsel challenged whether Professor Stott was testifying in the capacity of an expert witness. To which the witness replied:
14
“…I’m slightly confused. So, I’m here as an expert witness and you’re asking me if I’m an expert witness?” 26
15
This motion is brought to clarify that Defendant’s hiring of Professor Stott with taxpayer
16 17 18 19 20 21
$50,000 to train Captain Brooks and Lieutenant Dyment in Europe [note: both of
dollars outside of the context of this litigation, does not prevent Plaintiffs from calling him as an expert witness. Defendant notably did not object to the taking of his deposition under Mothershead v. Adams, 32 Wn.App. 325 (1982). Nor did it invoke Crenna v. Ford Motor Co., 12 Wa.App. 824 (1975). Nor did Defendant raise CR 26(b)(4) since it only applies to experts expressly retained for litigation.

ER 702 provides:
2
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.
3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
The OIG hired Professor Stott because he is the number one expert in the field of crowd policing. He meets all the requirements of being an expert. See also WPI 2.10. The determination as to whether an expert witness possesses the necessary qualifications to testify on a proper subject is within the sound discretion of the trial court. Rice v. Johnson, 62 Wn.2d 591, 384 P.2d 383 (1963); Saldivar v. Momah, 145 Wn.App. 365, 397, 186 P.3d 1117 (2008) The OIG hired Professor Stott with government funds to perform governmental work. Because of the Public Records Act, Defendant cannot suppress discovery of his public written opinions or the taking of his testimony by Plaintiffs. 5. CONCLUSION The Plaintiffs’ intent to call Professor Stott as a witness with special expertise and knowledge, is no different than if they called a treating medical doctor. So long as the expert’s opinions are disclosed in advance, there is no requirement that plaintiffs must enter into an expert witness contract with the doctor. Indeed, most doctors would never so agree. Because Professor Stott’s testimony is central to the issues at bar and the defense protestation so vocal, Plaintiff’s request this ruling be made now. 6. PROPOSED ORDER A proposed order is attached.
