Stop the portrayal of guns & knives in film and game advertising

We can't stop violence in films, TV shows and video games but we can stop the glorification of that violence using guns and knives in adverts in media streams and posters. Knife and gun crime is on the increase and the message from these adverts is that it is OK to use them. If you choose to watch a film, TV show or play a video game then fine, but advertising is usually seen by all ages indiscriminately. Please help ban the use of guns and knives in all forms of adverting.
