And? One sees it a lot in our town, some groups when they walk past police pull hoods down over their faces, scarves up, turn their faces away -- we have a lot of drug selling, these people match the look of those you see dealing/running (deliveries); or those who do the organised shoplifting.

Whilst the rest of us may have lots to hide, our physical appearance isn't one of those things because we don't expect to be subjects of active investigations.

Maybe that'll change?
