But you are very wise to draw together the conclusion from both Josh's trial and Kirby's deal. Both were 'loitering' around a business with an openly carried firearm in Vancouver. Generally, I don't just hang around while I OC. I continue to shop or go about my business. This was the same before I OC'd and was a CCer. Note that both Josh and Kirby were outside of the business when ticketed.
My suggestion is to not loiter outside of a business while OC in Vancouver. Go inside and shop.
