Labels are not going to include anything the government doesn't require, and without adequate studies reporting the drugs can/may cause violent behavior, you should look beyond the FDA's viewpoint.
This is from a Swedish study:
Using large national registries, over 850,000 individuals were identified who were
prescribed an SSRI medication. The authors then quantified the cumulative dose
of SSRIs and divided subjects into groups of low, moderate, and high. From other
registries, arrest and conviction records were examined and compared to the
medication histories.
The main finding of the study, and the one that received the most press, was that
for both males and females between the ages of 15 and 24 only, there was a statistically
significant increase in the rate of violent crime during the period someone was taking
the medication compared to the intervals when they weren’t. The “hazard ratio” for the
15-24 age group was 1.4 which roughly translates into a 40% increased likelihood.

We are talking about a class of drugs, not a single formulae. When someone is beginning treatment using these drugs, the doctor basically becomes a Rx dispensing optometrist.
Gives you a prescription. "Is your mood better, or worse?"
If worse or no improvement, they try a different prescription. "Is your mood better than before this prescription, or worse."
The doctor is 100% reliant on the patient to express how they feel to know if something is working. Also, since the various drugs being prescribed work in some people and not in others, it's reasonable to assume the same drug in 2 patients can make one better and the other turn to thoughts of suicide or hurting others.
Studies are the same way. not only is measurement difficult, but the same drug take by one random sample may have different side effects than when taken by another sample. Unlike most drugs, psychotropics have a wide range of effects on the human brain. Tylenol might work on most of us, but psychotropic effectiveness varies widely.
I think there are plenty of warnings if you do some research. They just haven't been forced on the drug makers to be printed on a label -- yet.
Some folks have put a lot of work in compiling this information for us, but the gov't isn't about to blow the whistle on Big Pharma -- think of the lawsuits if their drugs are directly linked to school shootings and other acts of extreme violence.
