I'm not going to be scouring the internet to find a specific quote under LA law, but all the States and Canada are very similar in this area. Under Canadian law, the police can use as much force as necessary to take someone into custody under the Mental Health Act. Taking someone into custody sometimes involves the use of force, and the police are supplied with a use of force continuum. Someone wanting to run into a an oxygen deprived environment filled with volatile organic compounds is not of sound mind, and easily falls into this category.That has nothing, I mean absolutely nothing to do with this.
Get back to me.
Do the research yourself or ask a police officer, but from what I've read, the police are well within their legal authority.
PEACE OFFICER'S POWER TO TAKE INTO CUSTODY
Peace officer's power to take into custody
12(1) A peace officer may take a person into custody and then promptly to a place to be examined involuntarily by a physician if
(a) the peace officer believes on reasonable grounds that the person
(i) has threatened or attempted to cause bodily harm to himself or herself,
(ii) has behaved violently towards another person or caused another person to fear bodily harm from him or her, or
(iii) has shown a lack of competence to care for himself or herself;
(b) the peace officer is of the opinion that the person is apparently suffering from a mental disorder of a nature that will likely result in serious harm to the person or to another person, or in the person's substantial mental or physical deterioration; and
(c) the urgency of the situation does not allow for an order for an examination under section 11.
Bottom line whether you like it or not, there will be no charges against these officers.
I get it. You hate the police, but I'm telling you, you do not want to go back to the old days. It was more like LA Confidential than Andy Griffith back in the day.
