Unfortunately, for now, this happens worldwide.
The people unde age of 18 are classed as somehow "non-conscious" beings, meaning not aware or fuly able to comprehend the entirety of things and therfore, when those are doing wrong doings then the law is somehow more "forgiveful" towards them.
Although this is understandable in a way that does not mean that they should not face justice and be rehabilitated, giving green cards will only result in more wrongdoings.
As you've said, although you're Turkish living there your country and mine and more are influenced by the corrupts who seek only to do chaos and evil shit.
We are fighting to restore and even evolve the whole world towards it's fullest greatest potential, a world where everyone lives peacefully.
Whoever seeks to improve itself and do good things, I have absolute certainty and I lived it as I live now, the God's will do help and provide for as long as we trying and wanting to, genuinely, do better.
