Reading your reply, all I can say is, I’m relieved you are retired.
So lets say a loved one of your has a heart attack, and police cars are blocking the entrance causing a twenty minute delay . Would you be so kind to the police? The police call EMS instead of letting you through, and all they can do is give you oxygen, pain killers and aspirin while the definitive treatment ( heart cath or surgery) is a few feet away. But you are not allowed there. All the while your heart muscle is dying.
Those cops should not be blocking an ER entrance and you are a complete idiot and imbecile.
