I say bad reporting.
you never have a cop just take a person to an involuntary evaluation.
He had to have done SOMETHING.
Perhaps. Having been a cop for 30 years I can tell you that there are some very ignorant ones who have no clue what it is they are allowed or authorized to do and as a result screw up by the numbers more often than you want to know.
Also, having swat respond to such a call is nonsense.
