The Weapon behind the Joint

On it's 20th of August edition, "Público", the main Portuguese Daily newspaper has published a small article over the Boom Festival, the biggest Psy-Trance occurring in this country, with the title "Drugs and weapons apprehended in the Boom Festival".

In this small article, responsibility of LUSA news agency, it was reported the detainment of 17 persons accused of drug possession. From these 17, only six were prosecuted with possession and consumption of drugs, which were mainly haxixe.

However, three others were caught with illegal guns, that means, guns without a legal licence. These three persons were not detained, just identified for future purposes.
These behaviour from local authorities lead us to severe and several doubts over the security of the Portuguese community in it's all.
It seams that, under it's law, someone carrying joints is a further bigger threat to its community, than rather someone carrying a gun.

Nevertheless, the violent crime is rising sky high in Portugal and each year, a local phenomenon of violent killings in the big cities night life, is gaining dangerous and uncontrollable proportions.
Meanwhile, as the state and it's politicians pretend drugs don't exist, there are many being poisoned with adulterated stuff, while others make their biz, living and enriching with it. As they do, the state as a whole is losing the tax money from it's selling (as it happens otherwise in Holland) and, much worst than that, is losing the precise idea of how much is sold and how many consume, so true preventing policies can be defined to attack the problem. By prohibiting it, not only they enhance the health problem, as they loose it's true dimension.

On the other hand, people holding and carrying guns, which cannot be normally and mentally sane if they take them to a 25.000 people festival, are left free, without not even being presented to a judge to explain the reason of their act.
So, I leave here these questions to us all, hoping some politician, judge or officer might one day read these lines.

1- Why does someone take Haxixe to a Psy-Trance Festival?
2- Why does someone take a Gun(?!?) to a Psy-Trance festival?
3- Why is to the law, more dangerous to carry haxixe than a gun?

And if someone responds that is to defend himself, I leave therefore a final question:

Who or which law can defend us from someone taking a gun to a Psy-Trance festival or wherever else this person may go?
