I get the impression they held you because of your hearing impairment. The officer wasn't convinced that you were all right. Personally, I think this is an inane excuse, but I can see why it would be enough to justify a 72 hour hold. All someone had to do was take the time to communicate with you to confirm that you were not suicidal. Many healthcare professionals, even police officers, don’t know how to communicate very well with people who are deaf. I have seen it.

Sometimes, doctors get blinded by past history and the opinions of colleagues, including police officers. No matter what the patient says they are ignored. Any condition that hinders communication tends to worsen this.

Here in Ontario, police can detain and escort you to hospital, but they cannot admit you. A psychiatrist is the one responsible for that. Officers are not trained.
