It is that easy, if someone wants to kill themselves. Go step into traffic, hop out the window, OD on drugs in the cabinet, or grab a knife from the kitchen. Or, the old prison favorite: drown yourself in the toilet. Its not as if this "easy as blowing a raspberry" suicide is going to happen on accident, they still have to actually do it, and if they're going to do it, they're going to do it. If someone is going to chicken out, then they would do so before "blowing the raspberry." As I said, if someone wants to kill themselves, they're going it. If they don't, and are going to chicken out or are just doing it to get attention, then that will be revealed just the same. I don't think suicide rates would change at all.
