Over the last week or so, I've seen a lot of trailers for Channel 4's dispatches programmes on gun and knife crime.  They are pretty powerful.  Usually they are shown alongside adverts for computer games with names like 'brawl' or 'shoot up everyone in sight til they are well and truly dead' (OK I invented the second one but you get my drift).  Is there something a bit awry here or is it just me...? (that's rhetorical btw)
