Day three of the trial for the outgoing Surrey mayor heard from expert witnesses today. A biomechanical engineer testified that a car tire can run over a foot and not necessarily break bones. The court also released more surveillance video from the day of the incident when McCallum alleged his foot was run over after an interactions with a woman in a parking lot – Nov 2, 2022

Outgoing Surrey Mayor Doug McCallum‘s foot was, in fact, run over in a supermarket parking lot, and the woman who did it had been involved in a campaign of harassment against him and other city councillors, McCallum’s lawyer has told a B.C. court.

McCallum has pleaded not guilty to a charge of public mischief over claims he made that Debi Johnstone, a campaigner with Keep the RCMP in Surrey, ran over his foot outside the Save-On-Foods at the Southpoint shopping centre on Sept. 4, 2021.

In his opening statements on Wednesday, defence lawyer David Gottardi told the court that the speed at which Johnstone drove over McCallum’s foot with her Ford Mustang was slow enough that it wouldn’t necessarily break any bones, but was consistent with the soft-tissue injury he said he received.

Defence, he added, would show how the incident fits in the context of Johnstone’s history with McCallum.

“Ms. Johnstone’s conduct towards Mr. McCallum and other city councillors was objectively designed to exert deleterious pressure on her targets, and that conduct is, on its face, harassment,” Gottardi said.

And the facts of the case showed McCallum had not committed public mischief, regardless of whether or not he made any intentional or unintentional “embellishments” in his report to police, the lawyer added.

Gottardi said the defence expected to call four witnesses over the next several days, including several medical experts.

Testifying as an expert witness, biomechanical engineer Dennis Chimich referred to McCallum’s medical records, showing swelling on the front outside portion of the mayor’s left foot, which he said he would expect to be the area hurt if it was run over by Johnstone’s back tire.

He calculated the mass of that portion of the car to be about 413 kg, and referred to a pair of studies looking at foot rollovers, one involving live people and one involving cadavers in a controlled environment.

Those studies revealed friction injuries and abrasions, but few fractures in the live study and none in the studies on cadavers, Chimich testified.

“They concluded, ‘The lack of bone injuries or other serious injuries of the foot do not exclude the foot from having been rolled over at low speeds by a … vehicle. Rather, bone injuries are not to be expected at low speeds,’” he quoted from the second study.

“The absence of fractures or serious injuries for Mr. McCallum does not mean that his foot was not run over in this incident.”

Under cross-examination, Chimich said he had not included the speed of the vehicle or the pressure of its tires in his calculations.

Special prosecutor Richard Fowler questioned the study’s use of cadaver feet, suggesting age, medication or fluid retention could also cause swelling in a foot.

He also asked Chimich if someone who’d been hurt in this way would react by inspecting their injury, but was cautioned by Judge Reg Harris that the question would be better suited to a medical expert.

The court also heard from Bradley Heinrichs, a mechanical engineer with expertise in video analysis and crash reconstruction.

Moving frame by frame through a grainy, zoomed-in video of the encounter, Heinrichs told the court McCallum appeared to jerk his head and arms back as the rear tire of Johnstone’s Mustang passed him by.

Heinrichs also presented an aerial diagram recreating the path of the Mustang’s front and rear tires, plotted from a 3D model generated from the security video.

He agreed it was possible the rear tire could have run over McCallum’s foot, depending on where he was standing, but said the angle of the security camera made it hard to say exactly where the mayor was positioned.

Wednesday’s proceedings concluded with testimony from Hamed Basseri, the radiologist who examined the X-Ray of McCallum’s foot at Peace Arch Hospital, several hours after the incident.

Basseri testified that he observed swelling on the outside of McCallum’s left foot, towards the small toe, but said he did actually examine McCallum’s foot.

Under cross-examination, he said he did not view an X-Ray of McCallum’s right foot for comparison, nor could he determine when the swelling originally started from the scan.

On Tuesday the lead RCMP investigator in the case testified that surveillance video from the store was inconclusive in determining whether McCallum’s foot was run over, but that there’s enough evidence to suggest some of his claims were false.

The court has also heard testimony from Johnstone, who said she yelled at McCallum to resign and exchanged in an expletive-laden “heated debate” with the mayor, but denied running over his foot.

The trial has now recessed until next Tuesday.
