The fire that woke up a city and afterwards a country

I just heard about the deaths in Santa Maria (RS). More than 200 people lost their life in a night that was suppose to be remembered as fun. Mostly, if not all, still learning who they were and the way they were going to follow. University students having fun while they still can. In this scene appears an irresponsible musician that decides to fire a firework or something similar indoors and the lack of preparation for emergencies. Did this club have a license? How come a place that apparently can take ~1000 people has only one small door? This was a tragedy that shocked the world. This is just an unfortunate tragedy that may have to happen sometimes to make things change. I hope they do. I hope many other things change. Justice has to come back to Brazil and make living there more safe. Since I am living in Europe, people ask me if I plan to go back. All I can say is that I hope to stay here. Life is so much easier when one don't have to worry about safety. This brings me really unhappy. Brazil is not even the worst case scenario in the world. Things need to change and I hope to be of any help.
