If he is a danger to himself or others, the police can do an EOD - Emergency Order of Detention.
Basically, that means they take him into custody and transport him to whichever mental institution Choctaw uses (here in Seminole County, we use Grifiin Memorial in Norman) for an evaluation.
This will do a couple of things.
1. It will get him out of the picture for awhile, which will help your sister pull her head out of her ass.
2. It may or may not get him committed to the nervous hospital, depending on the outcome of his evaluation and the decision of the judge.
Also, falsifying a police report, that he obviously has done, is also a crime. He can be jailed for that. He can also be jailed for public intox - drugs.
thanks i will try this.
