The basis of “Red Flag” laws.
The police don’t need no reason or justification. Those political connected will not be touched.
Unfortunately it takes years to play out.
All 50 states have,for many years,had well established laws giving police the power to take a person who displays certain degrees of mental instability into custody and deliver that person to a psychiatric hospital.I know this because I worked in a big city ER for years and saw that happen on more occasions than I can recall.
Once such a person is hospitalized it's up to medical professionals to determine how serious,and how long lasting,that condition or those symptoms are.And,of course, the courts are involved in all such cases.
IOW,the police already have the power...even without these "Red Flag" laws...to take an "unstable" person into custody.And,to repeat,that's true in all 50 states.
