If only all Americans got these kind of expose's after the media reveals they had an ounce of weed on them.

I frequently see the suspect/victim/dead person/perp's association with drugs as a reason why their life is worthless. I've seen instances in some departments where the police just stand on the victim until all the life is gone, or the paramedics never arrive, or the paramedics just nonchalantly go through motions but never attempt resuscitating.

I would just assume all these contrasts would be fresh on everyone else's minds too.
