It’s a Toronto Police press conference. Two individuals walked into a jewelry store wearing burkas and cleaned it out at gunpoint. They were not muslim women, but allowing a segment of society to normalize such clothing created a situation where the criminal’s “disguise” raised little notice or suspicion as they travelled to and from their mark and made them near impossible to identify. I believe the violent crime remains unsolved.
