This mural talks about the violence that society is experiencing and many people suffer daily both explicitly and subtlely. Oppression is being exercised against all dissidents and it is now more necessary than ever to reaffirm freedom of expression and criticise systemic violence. To do so, it is necessary to clearly show the violence which, in the case of the mural, points to the scientific world as a clear focus where arguments and debate are being neutralised by very specific interests.
