I'm not a fan of anything that involves another person.
I'm not a fan of the police, but still- they don't need your death on them. Same as jumping in front of a bus, or crashing into a semi, or laying on a train track.
Yeah, it might be easier than finding a method that you can do on your own- but you will absolutely cause the cop, driver, or conductor significant trauma.
I understand that my exit will hurt my loved ones. That's bad enough- I would prefer that it didn't also hurt random other people.
