light punishment for weapons offences

In a case in which a man was accused of carrying and transporting a weapon, an offense with a maximum penalty of 10 years, for possessing an air gun, it was proven, through ballistic calculations and penetration energy calculations, that it is a tool whose lethality touches the lower threshold and that it ceases to be lethal after a range of a few meters!
Despite being a police "target", meaning that the police were "looking" for him, and despite the stricter punishment policy for weapons offences, he was sentenced to only 10 months in prison, which he "spent" in the house arrest he was previously sentenced to.
