People who want to commit suicide find a way.
A number of years, a guy I had worked with for awhile when we were both freelancers at the same assignment became a friendly acquaintance outside of work. We did a couple of canoe trips (day paddles) together, hung out with some of the same people, etcetera. He was also pretty good friends with the office administrator where we were working. At one point the admin became concerned about the guy's mental state. I'm not sure how she managed it, but she got him into a mental health center for a three-day evaluation for suicide risk. At the end of the three days, they decided he wasn't at risk, so they sent him home.
He then climbed into his pickup truck, drove down the road a couple of miles from his house, and parked the truck across the main Amtrak line that ran through town. He picked a spot where both the road and the rail line were cut through a huge rock outcrop, and the rail line was on a curve so there was no way the engineer could have seen the truck in time to slow down.
So, if this had happened in 2022 and they had taken guns away from him because he was at risk -- would they have counted his case as a suicide prevented, because he couldn't shoot himself with the gun they took away?
