It's actually quite common to be sectioned and discharged a number of times, and is most definitely not an indicator of violence in and of itself. this goes fro both people who have psychotic episodes and thoase with repeat sections for depression (as in danger of suicide?)
Because of this assumption, and a post upthread being frightened of "someone behaving oddly in the street", I'm giving you the stats. Note: this is an AI quote, but I have checked out the articles where the information is derived from as can you.
"Most are not violent: Roughly 90% of individuals with psychosis are never violent, and they are far more often a danger to themselves (through suicide) than to others.
Victimization is more common: People with severe mental illness are nearly three times more likely to be victims of crime compared to the general population.
Small, specific risk: While most are not violent, the risk of violence in people with untreated, severe psychotic disorders (particularly paranoid schizophrenia) is higher than in the general population, often due to persecutory delusions where they fear for their lives.
Substance misuse is the key factor: Almost all of the increased risk of violence associated with psychosis can be attributed to comorbid substance abuse rather than the psychosis itself.
Context of delusions: In rare cases of homicide committed by someone experiencing psychosis, it often stems from intense, delusional, or paranoid beliefs rather than premeditated, stereotypical "killer" behavior.
