He does not appear to be a danger to himself or others. Why should he be forced to undergo severe psychiatric treatment?
@PC -- I stand corrected. I was not aware of some of Mr. Briggs more outrageous behavior. However, as near as I can tell, he behaves that way in an effort to induce other boxers to agree to fight him in the boxing ring for money. Perhaps he is "crazy" in the same way Donald Trump is "crazy" in running for President.
righty1, I won't deny he's made money at it. Some of the most obnoxious people are some of the richest. Thank you for your take on this.
