Shoplifting

Yesterday I watched a man in his late 60’s walk out the in door at No Frills with a knapsack full of food…alarms sounded and not one cashier turned to look. Today I watched a guy walk out of Dollar Store on Savage road with a duffle bag full of items ..I asked if he intended to pay them and he pulled his mask and pushed past me. The staff seemed indifferent when I told them he was shoplifting ..this guy was relatively well dressed in his mid 30’s. I guess this is just the natural progression (or erosion) of society …..what’s the protocol here as alternative to watching it happen?
