Go and see a personal injury attorney as soon as you possibly can.  The police put your Husband on grave danger by ignoring - or just not knowing - the symptoms of a stroke.  The fact that they mistook it for being intoxicated is a travesty of justice.  And when his BAC registered as 0 a light bulb should have gone off.  I would not only seek damages (I a sure that your husband's recovery was in some way hampered because of their failure to get him to a hospital) I would file a complaint as to the officers and I would make the biggest public stink that your police force does not know the difference in an emergency situation that could mean life or death to its citizens.  Good luck to you.
