This is very sad. 1 year of prison means completely ruining someone's life, especially if that someone is a 19yo guy.
And for what? A prank that did not really harm anyone.
The guy did not kill anyone nor did he commit acts of thievery. When will the law understand that, while unlawful, his actions where not that of a REAL criminal?
If I was the judge I would not be able to sleep at night, ruining the life of a kid playing a prank 🙁
