A manifesto allegedly written by the suspect, 104 pages in length, has been circulating online.

It does not use the term “incel” but has been described as being incel in nature. The term, short for “involuntarily celibate,” is a label used by people who describe themselves as unable to form romantic or sexual relationships despite wanting them.

Article content

The manifesto often uses the term “biological imperative” to describe the behaviour of men and women, arguing that men are inclined to seek many partners, while women focus on a small number of highly desirable men, leaving many average men or “common males” isolated. Much blame is levelled at what it calls “high capitalist” societies.

Some online incel communities have become associated with misogynistic views that blame women for these perceived romantic failures.

The manifesto, which is written in the form of a scientific paper, with subheads and footnotes, ends on the phrase: “Be unflinching, go forth, and KILL THEM ALL!”

The Canadian Press reported that a police spokesperson in British Columbia said forces across the province were warned after the shooting of the possibility of an anti-police manifesto.

Lindsey Houghton with the Surrey Police Service told the outlet.
