Good question. I have nothing to contribute to answer your question, but perhaps I can point out there are good reasons to be concerned...
A real story I came across on the net. I only copied and pasted what I view as relevant to this post. You can read the whole article at http://seattletimes.nwsource.com/html/localnews/134480964_deputy24m.html
Herzog, who was wearing a protective vest, had been sent to the Newport Crossing Apartments at 7311 Coal Creek Parkway S.E. in Newcastle, southeast of Bellevue, just after 5 p.m. in response to a report of a naked man dodging cars in the street.
Newcastle contracts with the county to provide police service. Herzog had worked in the six-man department the past two years, said Newcastle Police Chief Shawn Ledford.
Herzog was the only officer on duty at the time, Ledford said.
"That's not unusual," the chief added. "It varies; sometimes we have two people on per shift, sometimes one."
Ledford said Herzog, after arriving, called for backup from the sheriff's office, which patrols surrounding unincorporated areas. Ledford didn't know if Herzog had called before or after he got out of his car.
Witnesses and police say the deputy got out of his car and attempted to calm Matthews, who had been wandering through traffic and had stood in front of a Metro bus.
Moments later, the deputy sprayed the naked man with pepper spray to try to subdue him.
According to witnesses, the two scuffled and the man grabbed Herzog's .40-caliber semiautomatic Glock handgun.
Herzog retreated, and police and witnesses say the assailant repeatedly shot him. Some witnesses said the man stood over the fallen deputy and fired several times from nearly point-blank range.
"It certainly appears," Reichert said, "that Deputy Herzog was executed."
So... I, too, would be curious to know what are the LEOs options when their pepper spray fails, which DOES happen.
