Last year me and a friend witnessed a shooting (from quite a distance) in the east of Amsterdam. Moments later we found ourselves laying face down on the ground with Police pointing guns at us. The situation was quite sketchy, mostly because the Police thought we were armed. I realised how much unnecessary danger, fear and stress (and sometimes even death) is caused just because of situations like this.
So I put some money together and made some pins! Pins might not change the law, but they may help to change opinions.
