Students are allowed to play violent games.. Why

Bechause students arent animals that go act out the violent games in society. I have been playing violent video games myself since my early teen years and Ive never even been in a fight.. and I have no intentions of getting into one.. Parrents and schools tend to blame videogames for their kids behavior instead of taking responsibility for it. Its always easier to point the finger away from yourself. So why are students allowed to play these games? Bechause the majority of people have realised that violent behaviour cannot be blamed on videogames alone..
