GlaxoSmithKline paid the Department of Justice $3 billion for covering up evidence of this while promoting their SSRI to under-18s. They paid the fine in 2012, 11 years ago. The medical trial was done in 1994-1998.
In 2003, the (UK medicines regulator) MHRA obtained full clinical data from Glaxo, and based on that data forming robust evidence of significant increase in suicidality, both the MHRA and the FDA immediately said that paroxetine couldn't be prescribed to under-18s.
The UK govt rules on how to report medical trials were changed in relation to what happened with the publication of the Glaxo Paxil trials.
GSK paid around $1 billion in the 2000-2010s to settle several hundred lawsuits, including many many suicides and several family annihilations.
The main investigative news TV show in the UK, Panorama, reported on this in 4 shows between 2002 and 2007.
The Boston Globe did significant investigative work on this around 2005, including a book published by their reporter.
In view of that, your question comes across as at best, uninformed and naive.
