Not recommended. And not for any bootlicking reasons either. I despise law enforcement (at least of the American sort). The thing is, they have S-awareness training, and they are, by their nature, assholes. Once you confirm via your actions you want to die, you're getting wounded and thrown into a mental care facility. It's only when you're Daniel Shaver, Orlando Castile, George Floyd and the like that you'll actually die. Hint: none of those victims wanted to die. The lawman will see what you're trying to do and use your pain and plight to make himself a hero.
"Officer Baggadonuts is commended for not taking the life of a disturbed individual today downtown. He will be awarded the medal of exemplary service for his efforts in a non lethal deescalation of the event. More today at 6."
Take it from someone who lives in a state where cops do what they please: you'd better hope you have a fool-proof plan if you plan to go that route. Cops love to kill people, but only on their own terms.
